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”.

    My daughter had two goldfish given to her but one has suddenly got white spots on its gills and along the side of its front fins but the other one doesn’t. Does this mean one has ick or that its a male in breeding season?

      From what I’ve read online the one with the white spots is a male; the white spots mean he’s reacting to the pheromones given off by a female ready to spawn. We isolated our reacting male with the female he was chasing, and now, about a month later, we just spotted eggs in their tank today! So the fish go back into the main one and we’ll see if they’ll hatch! And it means that info is right. :-)
