Q. Do goldfish lay eggs?
A. Yes! Goldfish do lay eggs!
Do goldfish lay eggs?! Oh yes. Goldfish lay lots of eggs. A female goldfish can lay several thousand eggs in one spawning!
Selective breeding has led to thousands of varieties of goldfish, however, goldfish are not easy to breed and it’s extremely unlikely that goldfish will lay eggs when kept in a home aquarium. In order to breed goldfish need quite a big tank, lots of plants, the right temperature, and usually need to be a few years old.
Also, you won’t be surprised to hear that goldfish eggs don’t look like the eggs in this picture! Goldfish eggs actually look like small round “bubbles”. They’re clear in color except for a small dark spot in the middle of the egg. If your goldfish do lay eggs then you’ll probably find them attached to a leaf or piece of plant.
It’s because goldfish lay eggs – rather than live young – that there’s actually no such thing as a “pregnant goldfish”.
