do guppies lay eggs“Do guppies lay eggs?” is a very popular question.
Many people assume that guppies lay eggs – and that no fish ever give birth to ‘live’ young – but is this true? How likely is it that you’ll find guppy eggs in your tank tomorrow morning? If guppies don’t lay eggs then what is it like when a guppy gives birth? Read on to find out!

Do guppies lay eggs?

The answer to this question is… NO! 

Guppies do not lay eggs!

Although many fish lay eggs (goldfish, for example) not all fish lay eggs. Some fish – including guppies – give birth to ‘live’ young. This means that the baby fish (which are known as “fry”) start swimming as soon as they emerge from their mother. They’re not contained in any kind of egg – they pop out of their mother and swim off straight away! Fish that give birth in this way are known as ‘livebearers’.

If you plan to breed guppy fish then it’s important to understand that guppies are livebearers, as you will need to be prepared to care for the guppy fry as soon as they are born.

For example, you will need food for the fry and a separate tank for them to live in. A separate guppy fry tank is needed because baby guppies are very small and very vulnerable to being eaten by larger fish that see them swimming around the tank.

Even mother guppies will sometimes turn round and eat their own fry seconds after giving birth to them! For this reason, guppy fry should be removed from the main tank and placed in a separate tank, away from the other guppy fish, as soon as possible after birth. You can return the guppy fry to the main tank once they are bigger than the other guppies’ mouths!

  3. I’ve always wondered about that, because I’ve seen a lot of these tiny freshwater fish and yes, normally they lay eggs. Glad to know that guppies are among the few exceptions. Thanks for the info Guppy Fish Care!
