Most fish reproduce by laying eggs. The male and female release their eggs and sperm at the same time and the water mixes them, causing fertilisation. With a few notable exceptions (like the cichlid family) the eggs are then abandoned. Huge numbers of eggs are produced to ensure that some survive, and the babies (fry) are tiny - most die. Livebearers are fish that give birth to live young. They use internal fertilisation - the male has an organ, usually a modified fin, that he uses to transfer his sperm into the female's body to fertilise the eggs. The eggs then develop inside the mother. Usually, fewer eggs are produced and the fry, when born, are larger and well developed compared to egglayer fry. This means that a far higher percentage of them survive. The most common livebearers are the poecilidae. This family includes the aquarium favourites guppies, mollies, platys and swordtails. Other livebearing fish include the closely related goodeids, the pike livebearer and some marine fish including most sharks.

What is livebearer fry fish food?

Which word do you not understand? A "Livebearer" is a species of fish that has live babies rather than lays eggs. "Food" is a name given to what all fish including livebearers eat. "Fry" is the English word for most baby/infant fish. So "Livebearer fry fish food" would be food that is made specifically for baby Livebearers. Edit: I think you want to know what to feed livebearer fry, yes? If so, you can feed them crushed up flakes (REALLY small) or buy a product called Liquifry for Livebearers.

When a livebearer female is close to giving birth she often hides because she doesn't want other fish around to eat her fry. This could also be a symptom of a disease. It's impossible to know without more detail or a list of the individual fish's symptoms.


Will a baby fish die if it is let out to early?

It depends on whether the fish is a livebearer or not...most fish lay eggs, however Guppies and some other fish give birth to live young.I've never heard of a baby fish being born "too early" because the mother can choose to abort the drop (I'm going to assume that we're talking about livebearers) or even absorb it back if she undergoes too much stress.One thing that you should be careful of is that the parent fish eat their young.


You have raised a guppy that as it grew was a female then it got the male part on it its length and finanage of a female but has the male part on doesnt breed like a male fully grown witch is it?

If the fish has a triangular anal fin it is a female. If the anal fin is elongated and has a long point it is a "gonopodium" and the fish is a male. That is the ONLY WAY to sex a livebearer.
