Fish Breeding

Egglaying and livebearing are the two strategies exercised by fish. As what their names suggest, egglaying fish lays eggs rather than giving birth to a little look-alike of an adult fish as what livebearing fish does.

Do fish lay eggs from their mouth?

No, they come out of a small tube under their body close to the tail fin called the ovipositor. There are, however, some fish commonly called "mouth brooders" that will either scoop up the eggs into their mouths and keep them there until they hatch or will keep the fry (baby fish) in their mouths until they're large enough to stand a better chance of surviving.

How can you breed parrot fish?

Indeed blood parrots are hybrids between the 'Red Head Cichlid' and the 'Red Devil' (or I would guess sometimes 'Midas') cichlid. My personal experience that a number of forums will agree with is that the females for the majority fertile. However, the majority of males are sterile like the flowerhorn cichlid (another hybrid). If you pair a female blood parrot and a male Central American cichlid (no South American ones) and they lay without any other complicating factors you will get fry. A good example of a blood parrot hybrid is the jelly bean parrot (or just jelly bean cichlid). The only other thing to consider is that blood parrots are occasionally hormone treated to bring out adult coloration quicker because they 'fade' into their orange color the same way Red Devils do. I have been told that these treatments can make fertile fish sterile compounding the situation.

How do you breed Betta fish?

Breeding Bettas is a difficult and challenging endeavor. Also an expensive one. You will need a brooding tank that is no smaller than 10 gallons, a 40 to 50 gallon growing tank for the fry to grow up in, and upwards of 500 individual jars to put the new Bettas in once they are large enough. You will need a salt brine culture to feed the new-born, then a daphnia culture to feed them on once they are large enough. You will need a large room dedicated just to breeding and raising your Bettas. Unless you have lots of time, lots on money, and lots of space it is best to buy your Bettas from your local pet store.

if you have more than one betta fish, i advise you to put them in separate tanks because if you put more than one beta fish in one tank they would attack each other and they might die. When i was taking care of a beta fish i fed it three times a day and it worked out perfectly fine. if you want more information you should ask a pet store that sells betta fish.
First you need a 24"x12"x12" tank, a heater/thermostat set at 79F. Soft water and a mature pair of Beta splendens in breeding condition that have been kept apart. Some floating plants will help the male with his nest so they are a good idea too as is a few little hidey holes for the female to hide in when the male gets too rough. Add the female to the breeding tank first, wait overnight and add the male the next morning. Keep an eye on them. The male will start off by showing off (flashing his fins etc) to the female. He will build a nest of bubbles and plant bits and he will regularly drive the female under it. She will not stay until she is happy with the nest. Once she is happy they will take a position under the nest and the male will embrace the female and they will roll over trembling and then as they separate, the eggs (ova) will fall towards the bottom of the tank and the male will collect them in his mouth and blow them into the nest. This will continue until she is spawned out and the male drives her away. The female must now be removed from the tank before the male kills her.

Can a Central American salvini cichlid egg layer crossbreed with South African peacock cichlids frontosas or mbunas mouthbrooders As I have a female egg laying salvini cichlid but no male?

In addition, as it would not allow me to type any further, eggs have been laid by the female salvini central America cichlid, but as stated no male exists in tank of that area, other tank mates include mouthbrooders such as frontosa, peacock cichlids, and mbuna's all from south Africa, so I am curious if there is any possiblity that these eggs are fertile, as I have many breeding pair, but the female that has laid these eggs is the only egg layer in the tank and has no mate of same genre, any ideas if eggs could be fertilized by a mouthbrooding cichlid such as the tankmates from south Africa?

Where do Goldfish Originate?

In China, then they went to Korea, Japan, and Europe. They were bred from wild types of carp, around 960-1279 AD .

Here is a bit more information for you in addition to what someone typed above!

The Goldfish, Carassius auratus, was one of the earliest fish to be domesticated, and is still one of the most commonly kept aquarium fish and water garden fish. A relatively small member of the carp family, the goldfish is a domesticated version of a dark-gray/brown carp native to East Asia. It was first domesticated in China,960-1279 and introduced to Europe in the late 17th century. Goldfish can grow to a maximum length of 23 inches (159 cm) and a maximum weight of 9.9 pounds (4.5 kg), although this is rare; few goldfish reach even half this size. The oldest recorded goldfish lived to 49 years, but most household goldfish generally live only six to eight years, due to being kept in bowls. The collective noun for a group of goldfish is a "troubling."

In 1162, the Empress of the Song Dynasty ordered the construction of a pond to collect the red and gold variety of those carp. By this time, people outside the imperial family were forbidden to keep goldfish of the gold (yellow) variety, yellow being the imperial color. This is probably the reason why there are more orange goldfish than yellow goldfish, even though the latter are genetically easier to breed.

During the Tang Dynasty, it was popular to dam carp in ponds. As the result of a dominant genetic mutation, some of these carp displayed gold (actually yellowish orange) rather than silver coloration. People began to breed the gold variety instead of the silver variety, and began to display them in small containers.

The fish were not kept in the containers permanently, but would be kept in a larger body of water, such as a pond, and only for special occasions at which guests were expected would they be moved to the much smaller container.

The occurrence of other colors was first recorded in 1276. The first occurrence of fancy tailed goldfish was recorded in the Ming dynasty. In 1502, goldfish were introduced to Japan, where the Ryukin and Tosakin varieties were developed.In 1611, goldfish were introduced to Portugal and from there to other parts of Europe. Goldfish were first introduced to North America around 1850 and quickly became popular in the United States

The Shubunkin goldfish was developed by Japanese goldfish breeders that wanted to create a brightly coloured goldfish that still had the physical strength and survival skills of the common goldfish. Shubunkins are the result of selective crossings between Comet goldfish and Calico Fantail goldfish.

How do Betta fish breed?

In order to breed bettas, you can purchase what is called a breeder tank which keeps the female safe from the male until he is ready. His signal that he is ready to breed is by building a bubble nest.

Once the bubble nest is complete, you can release the female into the tank with him, and he will basically squeeze the eggs from her.
Once this is done, you should remove the female from the tank, and the male will tend to the eggs.

Breeding bettas is potentially deadly to the female, so this should only be done by someone with enough experience breeding bettas

Is a Golden Rainbow Trout an albino?

No, it is not an albino. An albino by definition is a "an animal or plant with a marked deficiency in pigmentation". The fact that these trout have pigment means they are not ablino.

What they actually are called is "Palomino Rainbow Trout". The Golden Rainbow Trout originated from a single Rainbow Trout that was spawned in the fall of 1954 in West Virginia. This trout's body color was a chimera of golden and normally pigmented tissue. When this fish was crossed with a normally pigmented Rainbow Trout, the offspring (what we have come to refer to as Palomino Rainbow Trout) were lighter in color.

I caught one this past Saturday here in Oklahoma.

How long is the gestation period for a fish?

This will depend on the type of fish. Most common fish such as goldfish are egg laying, so they do not get pregnant. Other fish such as Guppies are livebearing fish, and they have a gestation period of around 28 days

How do you breed Siamese Fighting Fish?

You have to have two tanks (10-20 gallon). First put the male in(the male should have more colour then the female)the tank wit out any other fish in but have plant in the tank when he is in condition he will build a bubble nest.Next introduce a good condtioned female. The male will be interested in the female under the bubble nest. As each egg is laid and fertilized he will blow a bubble around it and put it in the bubble nest. when the spawning is finished remove the female and the male will protect and care for the fish.
So that you may understand or retain the information, if I were you, I would go to the internet and type in betta breeding, so you could print yourself a copy of how to breed bettas, go to a book store a pet shop and purchase a betta breeding book for future reference, their are many details that I might overlook if I had not only to type, or even explain to a person in general. There is a lot of time involved,that is why some call it a hobby.

What animals live in the lake biome?

It depends upon the stage that the lake is in, as well as the depth. A bigger, deeper lake is capable of supporting larger fish, like sturgeon, pike and trout. Most lakes have some sort of waterfowl, northern ones will have loons, and nearly all will have herons, ducks, geese, swans, and some will have storks and/or cranes. Frogs, newts, salamanders, lots of amphibians. Probably at least a few types of watersnake, maybe a lizard or two if it's somewhere warmer. Turtles, crayfish, oysters, mussels, snails, tadpoles and a lot of insects in nearly any lake. Mammals too, beavers, otters, muskrats, things like that. All sorts of fish; in Michigan there are bluegill, sunfish, bass-bigmouth and smallmouth, perch, rockbass, dogfish, and then carp-invasive from China.

Do angelfish eat their own babies?

Some angelfish do eat their own babies. Many do care and parent their young. The ones that eat them usually do it because of not knowing how to parent or getting bored with the babies. Many angelfish also eat the eggs that were not fertilized.
