Ways of Breeding fish Tawes (Puntius javanicus)

Ways of Breeding fish Tawes (Puntius javanicus)


The provision of quality seed in sufficient quantities and continuous is an important factor in the development of fish farming for consumption.

Effort is mostly done in Magelang District, as in the Village District Paremono Mungkid therefore supported the availability of good water during the dry season and rainy. Besides, it felt more rnenguntungkan hatchery operations because a relatively short time spent approximately three weeks - one month, and its marketing was easy.

tawes fish hatchery is there some way that hatchery fish in the ponds, hatcheries and hatchery in rice fields in the hapa. Here is a technique pembenihannya:

1. Holding elections
➢ To get good quality seeds and the number of lots in the hatchery Tawes need to choose a good parent with the characteristics:

a. Location of the anal opening is located relatively close to base of tail.
b. Relatively small head and pointed.
c. Large scales and regular.
d. Wide and solid base of tail.

Generally fish ➢ tawes males began spawning at age less than one year, and its parent tawes females at approximately age 1.5 years. To know that the parent fish tawes have matured genitals and ready to be cultivated with signs as follows:


a. Female parent
- His stomach expands towards genetal (release) if dirabalebih soft.
- Hole anal somewhat reddish in color.
- Close the gills when touched more slippery.
- When the abdomen massaged from head to anal direction will come out blackish liquid.

b. Male parent
When the abdomen massaged from head to anal direction will come out whitish colored liquid (sperm).

Close the gills when palpated feels rough.
- When the abdomen massaged from head to anal direction will come out whitish colored liquid (sperm).
- Close the gills when palpated feels rough.


2. Pond Preparation

Tawes spawning fish pond as well as a hatchery pond and the pond. Before used for spawning, pond dried.
Improvements constructed and the pond made elongated channel (caren / kamalir) of expenditure towards water intake of water with a width of 40 cm and depth of 20-30 cm.


3. Parent Waiver
The parent fish ➢ tawes who have been chosen to be cultivated later diberok, Pemberokan with the placement of the male parent and female separately for 4-5 days.
After diberok then inserted into the parent fish breeding ponds have been prepared.


➢ parent Submission to the pool when the water reaches approximately 20 cm.
➢ The number of the parent who removed 25 male and female parent male parent 50 tails.
➢ In the afternoon about 16:00 o'clock in the water entering the pond is enlarged so that the water flow faster.
Usually the parent fish ➢ tawes spawned at 19:00 to 22:00 o'clock.
➢ Parent will spawn normally have started at noon romp around the water intake.


4. Hatching Egg

➢ After tawes laying parent fish, the water entering the pond is reduced so that the eggs are not washed up, done at the hatchery spawning pond as well.
➢ In the morning checked if there are eggs that accumulate around the pool or the shallow part of the land distributed by swinging a broom stick in the bottom of the pond.
Tawes fish ➢ Eggs usually hatch all after 2-3 days.
➢ From the result of hatchery reared fish in the pond for approximately 21 days.

5. Fish Seed Harvesting
➢ Harvest conducted in the morning.
➢ dampen / drain the pond.
➢ After the seeds were dikamalir / dicaren, seeds are captured by the Waring or seser.
➢ The seeds are housed in hapa who have been placed in flowing water channel water flow is not heavy.
➢ Seed lersebut again later maintained in the pond or sold.


6. Separating
➢ At first pond dried for 2-3 days.
➢ Repair embankment, making caren / channel.
➢ Basic swimming analyzed using hoe, then fertilized with Urea & SP 36 10 gr/m2 and manure from 1 to 1.5 kg/m2 depending on fertility.
➢ After pool fertilized and then watered as high as 2-3 cm and 2-3 days later left the pool water added gradually until a depth of 50 cm.
➢ Then spread the seeds of the pond by stocking ekor/m2 10-20.
➢ Maintenance performed approximately three weeks - a month.
➢ The seeds can be harvested and the results can be sold or stocked in the pond anymore II.

EELS - Eerie Or Interesting ? Fresh Water

EELS - Eerie Or Interesting ? Fresh Water
by: Alex Royal


Next to sharks, eels have to be the most feared and misunderstood fish. Eels invoke thoughts of terror and wanton destruction. This may be because eels are similar to snakes, which also get little love and sympathy. Or perhaps this is another result of Hollywood's simplistic portrayal of this fascinating group of animals. In either case, the fear is unwarranted and one can successfully and safely keep eels in a home aquarium with a little planning and research.

While many people associate eels with saltwater aquariums, there are also freshwater eels, which means customers on both sides of the hobby can enjoy owning an eel.

Freshwater Eels

Almost all freshwater eels belongs to the fish family called Anguillidae and are in the genus Anguilla. There are 15 to 20 Anguilla species including the American eel (Anguilla rostrata). Many of these ells are important sources of food and are commercially grown on farms, especially in Europe.

Few of the Anguilla species are available in the aquarium hobby, however. Probably the most common freshwater eels in the hobby are from the genus Mastacembelidae which are not true eels but classified as spiny eels.The fire and the tire track eels are well-known members of this family available to hobbyists.

The fire eel (Mastacembelus erythrotaenia) comes from South Asia (Thailand through Indochina). The fire eels dark gray to dull black and has red and yellow horizontal stripes that extend from the head to the tail and look a bit like the fire flames painted on a hot rod. This coloration is how the eel got its common name.

The fire eel can reach a length of almost 40 inches in the wild, but aquarium specimens are usually much shorter but still large. This fish needs a large tank with a 55-gallon minimum tank size. Water should be a neutral pH and around 76 degrees Fahrenheit.

As with most freshwater eels, the fire eel prefers to dig and hide in the aquarium substrate. The tank should have a soft sand bottom substrate and flat to rounded rocks without sharp edges under which the eels can hide. Lava rock is not a good choice for an aquarium containing eels.

The fire eel is nocturnal, but can be trained to come out during the day to feed. In fact, a trait common to most eels, freshwater and saltwater, is that they can be trained to eat right from the aquarist's hand. However, eels have poor eyesight and it is not unusual for them to literally bite the hand that feeds them. This is not an aggressive behavior, but the result of poor aim on the part of the eel. Good choices for feed include beef heart, worms and cut fish and shrimp.

Another common freshwater eel is the tire track eel (Mastacembelus armatus). This eel grows large and, in many cases, is mean and aggressive. The common name comes from the color pattern on the sides of the fish that resembles the track of a fire. But this fish may run over any fish that gets in its way.

Most aquarium specimens start at about 6 to 10 inches, but they quickly double or triple in size. Chances are they will start looking at tank mates as swimming morsels of food rather than neighbors. This fish will need lot of room-an aquarium at least 75 gallons-and large tank mates.

They don't seem particular about water quality other than the normal values for nitrogenous waste, neutral pH and water temperature in the mid 70s Fahrenheit. Feeding is easy as they will eat most anything such as beef heart, bloodworms, insects, frozen food and cut seafood.

We hope that this guide was of help to you and your hobby.

THANK YOU...

feeding catfish

feeding catfish








catfish can be kept in fish ponds with ground or wall construction, the important construction of fish pond farming qualified and competent to be used as maintenance medium catfish.

feed given to the maintenance of catfish can be a pellet. Pellets are given as much as 3% of the total weight of fish that were planted and then divided by 3 to be given in the morning, afternoon and evening.

in addition to the feed pellets in aquaculture and catfish this could be the remnants of waste from restaurants, poultry slaughterhouse / livestock, snail, chicken feathers. The feed is an alternative feed that could be the best choice for catfish farmers

red tilapia

Known as Taiwan red tilapia or hybrid between 0. homorum with 0. mossombicus named florida red tilapia fish. Some suspect that the red tilapia is a mutant of the fish mujair. These fish into Indonesia in 1981 from the Philippines and in 1989 from Thailand.



Red tilapia cultivation has developed in some areas, even the production has been exported to Europe and the United States. White flesh and thick. It felt good, like red snapper. In some European countries, meat red tilapia utilized as a substitute for red snapper meat.


In cultivation, red tilapia fish have an advantage among others) of red tilapia fish response to artificial feed, 2) rapid growth, 3) can live in conditions of high density, 4) value of the ratio between feed consumption and the resulting meat is lower, 5) resistant to disease and water environment is inadequate, 6) sense of the meat tasty and much-loved community.


A. Systematics
Family: Chiclidae
Species: Oreochromis-niloticus
Trade names: red tilapia
Local Name: snapper merapi, mujarah


B. Darts characteristics Aspects Biology

1. Physical characteristics
Fish body rather round and flat. The mouth is situated at the end of the head (terminal). Rib line (linea lateralis) cut in half and lay lengthwise starting from the pectoral fin. Number of scales rib line as much as 34 units. Plain reddish body color or black-spotted, spots, and often colored albino (albino).



2. Growth and development
Red tilapia breed and are rapidly growing. In addition, these fish have a high tolerance for salinity changes until 30 promil. First maturity is reached at age 4-6 months with a weight of 100-250 g. These fish can breed 6-7 times / year.


A mother can produce as many eggs from 1000 to 1500 grains. When spawning the male fish will make a nest and guard it. The fertilized egg incubated by the female parent in the mouth. Guarding by females was continued until a week after the eggs are hatched.


Karamba in the floating net fish can reach sizes over 250 g in 4 months from the initial weight of about 20 g. male fish grow faster and larger than females.



C. Cultivation Site Selection

as belonging eurihalin fish, red tilapia fish can be cultivated in freshwater, brackish, and sea. However, in waters with high salinity (> 29 ppt) of this fish is still growing well, but can not breed. Red tilapia can grow well in temperate aquatic environment between 27-33 degrees Celsius; dissolved oxygen levels> 3 mg / l; a pH 7-8,3; alkalinity 90 to 190 mg / l; hardness 62-79 mg CaCO 3, the speed current 10-2o cm / dt, the brightness of> 3 m, and the depth of water 10-20 M.



D. Container Cultivation
Raft as the Karamba (where the fish in a lake or dam in the form of nets) can be made of wood, stainless steel pipe, or bamboo. Buoy plastic drum volume of 200 liters. KJA unit for measuring 5 m x 5 m,

requires 8-9 Buoy karamaba made from net material of polyethylene. Net eye size depending on the size of fish that will be maintained. In every corner of Karamba should be weighted by a stone or cast concrete weighing 2-5 kg. Anchor required to maintain the functioning of the raft drifted to avoid. Anchor can be made from metal, wood, and cement castings.


E. Cultivation Management

1. Provision of seeds
Seeding of red tilapia is generally directed to produce female seeds mixed male. Given the male fish have a larger size and speed of faster growth, many farmers led to the cultivation of red tilapia males. Therefore, the cultivation of fisheries experts have sought to create a red tilapia seeding technology with the use of male hormones 60 mg of mixed metiltestosteron
into 1 kg of feed larvae. Sex over the process lasts for 28 days



Transporting seeds should be done with an open system if it takes less than 4 hours. In the meantime, if more than 4 hours, transportation can be done with a closed system using a plastic bag which added oxygen.


2. Spreading
Spreading the seeds performed in the morning or late afternoon so the air condition is not too hot. Before stocking, be aware of water quality conditions. If the water quality of different transportation with locations of water quality cultivation, adaptation needs to be done slowly, especially for salinity and temperature. Solid optimal stocking to be applied is 500 ekor/m3 with initial weights 15-20 g of seeds per head and 3-month maintenance time for single-sex culture systems (males only).


3. Feeding
At the time this young fish-eating plankton, both vegetable and animal plankton. Adult red tilapia fish started to eat detritus and algae are also common threads. In addition to be herbivore, omnivore fish that can be given artificial feed (pellets). These fish response, the artificial feed (pellets), either sunk or floating pellets. Artificial feed is given pellets with 26-28% protein content as much as 3% of body weight per day. Frequency of administration 3 times a day, ie morning, noon and night.


F. Controlling Pests and Diseases
To know which way the disease and its prevention, diagnosis required symptoms. Symptoms of the disease for red tilapia fish cultivated can be observed by following signs tent.


a) Symptoms of skin disease
- Color red in certain parts.
- Skin changes color became more pale.
- The body slimy.


Control
1) Soaking the fish in a solution of PK (potassium permanganate) for 30-60 minutes at a dose of 2 g/10 l of water. Treatment done over 3 days later.

2) Soaking the fish with Negovon (potassium permanganate) for 3 minutes with a dose of 2-3,5%.


b) disease in the gills
Symptoms
- Close the swollen gills.
- Sheet gills pale / white.

Control
- How to control the same as skin diseases.


c) Diseases of the organs in the phenomenon
- The fish's stomach was swollen.
- Scales up.
- Fish is not nimble.
Control
- How to control the same as skin diseases.


The general things can be done to prevent diseases in the cultivation of red tilapia fish in the KJA is as follows.

1. Avoid over-stocking of fish exceeds capacity.
2. Give grazing, both quality and quantity.
3. Avoid the use of feed that is moldy.


G. Harvest
Red tilapia fish are maintained by stocking compact 500 ekor/m3 can be harvested after 3 months. Production and 85 kg/m3 Survival rate 85%. Harvesting fish in the KJA easy to do. Harvesting systems can be either total or selective depending on the needs.
Harvesting should be done carefully to prevent injury due to friction or other fish fin puncture. How to harvest is the basis Karamba slowly lifted. However, one side of the Karamba must remain in the water allowing fish gathered WAY. After that, the fish that have been collected and selected side karamba arrested using seser slowly.

Telur ikan gurame

telur ikan gurame

telur ikan gurame yang telah menetas, benih ikan gurame ini berumur 3 hari, benih ikan gurame yang masih mempunyai kuning telur belum perlu diberi makanan. Makanan diberikan pada benih ikan gurame ketika telah habis kuning telur, kuning telur
akan habis ketika umur benih mencapai 12-16 hari.
pakan yang diberikan pada waktu benih telah habis kuning telurnya yaitu berupa pakan alami yaitu seperti Daphnia, cacing sutra.
pelet tepung sebagai pakan buatan juga bisa diberikan pada benih ikan gurame, tetapi menurut pengalaman bahwa pemberian pakan
berupa pelet tepung tingkat keberhasilannya kurang bagus,
lebih baik benih ikan gurame diberikan pakan alami yaitu seperti cacing sutra. Kandungan giji pada pakan alami cocok diberikan
pada benih ikan yang masih kecil. Pakan buatan berupa pelet tepung diberikan apabila benih ikan gurame telah mencapai ukuran 2 cm.

tempat penetasan telur gurame bisa menggunakan akuarium, baskom, bak tembok, bak terpal, bak plastik. Kita bisa memilih salah satu atau beberapa tempat penetasan ini, yang penting dalam hal penetasan telur faktor yang perlu diperhatikan yaitu dari segi kualitas airnya. Kita bisa menggunakan aerator untuk mensuplai oksigen pada benih ikan, dan bila perlu untuk mempertahankan kestabilan suhu kita bisa menggunakan alat bantu pemanas air yaitu heater.

catfish meat characteristics

catfish meat characteristics

Catfish, including one freshwater fish species which, according to its fans have good taste and juicy flesh with a texture, soft. However, there are also some people that are less like him because he thinks catfish meat contains too much fat.

This assumption is not entirely wrong, because there is some meat that crumbled into pieces while frying. This happens especially on catfish large.

Based on our research, channel catfish has the nutrients high enough. Every 100 grams of beef contains 18.2 grams of protein. That way, 500 grams of small catfish (about 4 tail) contains 12 grams of protein, energy 149 calories, 8.4 grams fat and 6.4 grams of carbohydrates. Nutritional composition of this magnitude are rarely owned by the flesh-meat sources of protein. Currently, preparations are also catfish sold in restaurants, restaurants, hotels, and shops in the form of five feet, pecel, curry, or spicy tamarind flavored.

catfish ready for harvest

catfish ready for harvest

This catfish tail size 7-10 per kg, this catfish is ready to be harvested and marketed, the size of catfish like this are ready catfish consumed by us as a friend Rice.

Catfish are suitable used as pecel catfish. if the size is too big catfish are not suitable for consumption and general people do not like to eat adult-sized catfish.

excess of this catfish farming is that it can be cultivated in areas that lack water resources, because catfish do not have to require fast flowing water, enough with the small flow of water. we do not have to worry about the lack of oxygen in the pond, although oxygen can breathe a little catfish and take air into the pool water surface, because the catfish has additional respirator maze.

catfish fish classified as having the ability to grow rapidly especially when supported by the feed quality and fairly.

Enlargement of channel catfish in the pond tarp

Enlargement of channel catfish in the pond tarp

Catfish are freshwater fish that are common in public waters such as rivers, swamps, reservoirs, and other puddle. Catfish body shape is gilig (cylindrical) elongated, tapered flat head, and near the mouth covered with 4 pairs of elongated rigid whiskers. Catfish skin smooth, not scaly, and the color black. fish, including catfish, which easily cultivated anywhere, can live at an altitude of more than 1,000 m above sea level with temperature conditions of 20-32 ° C, pH 6,5-8, and 3 ppm oxygen content.

There are three types of catfish that used to be cultivated, including catfish local (Clarias botrocus), catfish dumbo (Clariosgoriepinus), and catfish sangkuriang. Catfish sangkuriang an improvement strains of catfish dumbo, the results of crossbreeding of batik from catfish dumbo derived from F2 (the descendants of the two) dams catfish dumbo with F6 (descendants of the six) male parental catfish dumbo.

fish Catfish dumbo is a type of catfish that have rapid growth, within 10-12 months of weight can reach 200-300 g. While local catfish growth was quite slow, for example, in the same time a new local catfish long as 20 cm with a weight of 150-200 grams.

Rearing catfish cultivation, from seeds to the size usually tersegmen consumption, which is based on the length of the body, such as 1-3 cm, 3-5 cm, 5-8 cm, 8-12 cm, to measure consumption is calculated by using weight like 6 tails per kg, 8 fish per kg, or 10 fish per kg.

1. Spreading seeds
Density stocking of which is often done by catfish farmers in the pool tarp around 100-300 fish per m2 with seed size 5-7 cm. Farming is done until the harvest or after reaching the size catfish consumption, which contains 8-12 fish per kg with long maintenance of about 2,5-3 months.
When the seeds are still rather small catfish, seed selection should be based catfish grade / level. selection is ideally performed every 10-15 days. This is done by the following considerations.

a. To avoid the occurrence of food seized each other so that the smaller catfish to be difficult to get the feed.
b. To avoid cannibalism among the larger catfish on a smaller catfish.
c. Balancing the growth of catfish because catfish are greedy, so the remaining feed from the feed portion size catfish will eat smaller larger catfish. In addition, this gluttony can cause abdominal swelling suffered catfish.
d. Saves given pellets and reduce pollution because the rest of the pool feed.


2. Feeding
The feed given to the seed catfish, ranging from the larvae (after starting to eat) until the age of at least two weeks to eat natural food of protozoa and zooplankton (Daphnia and moina). Catfish farmers in the pool tarpaulin used to provide feed silk worms as a natural food easily available and good nutritious. Furthermore,

catfish seeds can be given artificial feed pellets with a small size until the size of the pellets were adjusted to the size of the mouth of catfish. When the catfish was growing up, farmers used to feed a chicken carcass that had been burned or boiled, chopped snails / slugs, the remaining household waste, or feed ingredient itself in the form of pellets. The aim is to save costs for feed.

3. Treatment
Catfish, including fish species that can survive in water that is less good condition with a high density. This is because the catfish has a respirator alai labyrinth can be used to take oxygen directly from air. Therefore, many farmers are sowing catfish catfish with a high density to medium reddish water. In fact, there are some farmers who apply catfish cultivation without changing the water at all and only add water when the water conditions decreased the media.
Another case when the environmental conditions less favorable cultivation, for example in areas cold enough air temperature, water level should not be too high media-treatment is especially applicable when the catfish are still
smaller because the water is too high media can make a small catfish lost a lot of energy to swim, ie when the uptake of oxygen in the air. This certainly can affect the speed of its growth.

Controlling water also needs to be done when the rainy season, especially when the pond outside the tarp. Rain water entering the water can make the media environment becomes acidic and dangerous enough catfish. However, to maintain the health condition can catfish krosok scattered salt or table salt.

The history and origins of tilapia fish to come to Indonesia

The history and origins of tilapia fish to come to Indonesia

Tilapia fish was first imported from Taiwan to Bogor (Center Fresh Water Fisheries Research) in 1969. A year later, these fish begin to cast to some areas. Indigo naming provisions under the Director General of Fisheries in 1972. The name is taken from the name of this fish species, namely nilotica which is then converted into. Name nilotica showed these fish homelands, namely the river

These fish are naturally migrating from its original habitat in the river Nile in Uganda (the upper reaches of the Nile) to the south past kw Raft and Lake Tanganyika to Egypt (along the River Nile). Nila fish are also found in central Africa and west. Largest population is found in fish ponds in Chad and Nigeria. With human intervention, today tilapia has spread around the world starting from the continent of Africa, America, Europe, Asia, and Australia.


Classification
Initially, indigo included in Tilapia nilotica species or tilapia fish from groups that do not lay eggs and larvae in the mouth of its mother. In its development, fisheries experts to rank the species or groups Sorotherodon niloticus tilapia fish that lay eggs and larvae in the mouth of male and female parent. Finally, note that the incubating eggs and larvae ¬ in the mouth of the female parent only. Fisheries experts later determined that the proper scientific name for this fish is or Oreochromis niloticus Oreochromis sp. The following classification more indigo.

Phylum: Chordata
Subphylum: Vertebrata
Class: Pisces
Subclass: Acanthopterigii
Order: Perciformes
Family: Cichlidae
Genus: Oreochromis
Species: Oreochromis niloticus
Foreign Name: nile tilapia

Tilapia fish breeding

Tilapia fish breeding

By nature, tilapia mating in the waters all year round in tropical regions. The frequency of the largest spawning occurs in the rainy season. In its natural indigo can mate 6-7 times a year. These fish reach the adult stage at the age of 4-5 months and weighs about 250 grams. Productive spawning period is when the parent 1.5-2 years old and weighs over 500 grams per fish. A female tilapia weighing about 800 grams to produce as many larvae 1200-1500 tails every time mate.

Before mating, the male tilapia always make their nests in the form of spherical hollows in the bottom waters of the same diameter size. This nest is a territorial male tilapia that will be used as the location of spawning and fertilization of eggs. During the lust, the male indigo color will change to bright and very aggressive in nature maintain its territorial area.

Tilapia spawning process happened very quickly. Within 50-60 seconds the mating pair of indigo able to produce 20-40 eggs that have been fertilized. Spawning will occur several times with the same partner or different for 20-60 minutes. Tilapia eggs 2.8 mm in diameter, gray or yellow sometimes, not sticky, and sink to the bottom waters. Eggs fertilized incubated in the mother's mouth and will hatch within 4-5 days. Eggs that have hatched called larvae, 4-5 mm long. Newly hatched larvae reared by the mother until the age of 11 days (size 8 mm). The seeds that are not cared for by its mother will swim in a huddle in the shallow waters or on the edge of the pond.

Fresh Water Fish Bawal (Colossoma macropomum)

Fresh Water Fish Bawal

Bawal including one new commodity in the field of fisheries that have high economic value. Freshwater Bawal Latin names of fish Colossoma macropomum not native to Indonesia, but were imported from countries Brazil, South America a few years back. To distinguish bawal found in the sea, this Brazilian bawal called bawal fresh water because it is the whole life cycle in fresh water.


The first time you go to Indonesia, this fish is an ornamental fish to be maintained in an aquarium or garden ponds, but because the rate of growth is very fast and can reach large sizes, bawal freshwater grown less worthy of display. Because of that, supported by good taste and juicy flesh, bawal fresh water became very popular as fish consumption. The spread of these fish belong to very quickly that within a short time had a lot of farmers who cares. One thing is profitable, bawal fish freshwater fish species which are resistant to disease. So far have not heard reports of cases of disease dangerous to fish.

Tilapia fish breeding

Tilapia fish breeding

By nature, tilapia breeding all year round in tropical waters in the area. The frequency of the largest spawning occurs in the rainy season. In its natural indigo can memijah 6-7 times a year. These fish reach the adult stage at the age of 4-5 months and weighs about 250 grams. Productive spawning period is when the parent 1.5-2 years old and weighs over 500 grams per fish. A female tilapia weighing about 800 grams of larvae produced each time the 1200-1500 breeding fish.

Before breeding, the male tilapia always make their nests in the form of spherical hollows in the bottom waters of the same diameter size. This nest is a territorial male tilapia that will be used as the location of spawning and fertilization of eggs. During the lust, the male indigo color will change to bright and very aggressive in nature maintain its territorial area.

Tilapia spawning process happened very quickly. Within 50-60 seconds tilapia breeding pair can produce 20-40 eggs that have been fertilized. Spawning will occur several times with the same partner or different for 20-60 minutes. Tilapia eggs 2.8 mm in diameter, gray or yellow sometimes, not sticky, and sink to the bottom waters. Eggs fertilized incubated in the mother's mouth and will hatch within 4-5 days. Eggs that have hatched called larvae, 4-5 mm long. Newly hatched larvae reared by the mother until the age of 11 days (size 8 mm). The seeds that are not cared for by its mother will swim in a huddle in the shallow waters or on the edge of the pond.
