Do Goldfish eat their young ?
As a longtime Tropical aquarium hobbyist I know of several species that
eat their young after birth, hence isolation is critical. As a pond beginner I am not sure if Goldfish eat their babies. Can anybody expand on the whole breeding process of goldfish ? Do Goldfish multiply like rabbits ? Many thanks !! |

If you have plenty of plants for them to lay their eggs on and for the fry to hide and feed in, you will soon have plenty of baby goldfish to start giving away. -- McKoi.... the frugal ponder... ~~~ }((((o ~~~ }{{{{o ~~~ }(((((o |

Only once did I see a goldfish actively
pursue and eat an infant. I think it was a sociopathic goldfish. This fish tried once and the smaller one got away, then it came around and pursued it again, this time catching it. That fish was named Killer and eventually was given away in the great fish adoption. kathy :-) |

Young goldfish, about a month or two, will eat younger fish. The young are at risk just after they hatch while they are hanging on the side of things. Once they start swimming like fish are supposed to the big ones will pretty much leave them alone, with the exception of the ones I mentioned, the month or so ones. that's what I have seen, anyway. -- Charles Does not play well with others. |

My fish are well fed and I don't think I'd want this type of GF to breed and produce more like themselves. -- McKoi.... the frugal ponder... ~~~ }((((o ~~~ }{{{{o ~~~ }(((((o |

In my pond there are so many plants that all stages/ages of fry are visible by July. -- McKoi.... the frugal ponder... ~~~ }((((o ~~~ }{{{{o ~~~ }(((((o |

In the year before last I had a lot of anacharis in the pond and ended
up with 60-70+fry. Last year I did not have so much anacharis and had less than half the fry. In my opinion they do eat fry. They also eat the fish that die because three of my large goldfish are gone since fall. There are racoons and possums around but the fish were there when it iced over. When it started to melt I noticed fewer of the large fish came to the top. Happy water gardening. |

Can anybody expand on the whole breeding process of goldfish ? Do Goldfish multiply like rabbits ? As an aquarium hobbyist, you probably know that terms like "herbivore" and "piscivore" are completely relative with fish. Fish that can't live without greens are generally happy to swallow anything that happens to slip into their mouths, and even confirmed cannibals can be seen grazing on algae. Goldfish will eat their young, but they don't seem to really go out of their way for it. otoh, I've not seen them breed like rabbits either. Some of the stories I've seen here have been utterly suprising - one person saying she had 10 new goldfish last year, for instance - I'd say they generally breed much faster than that. But in 8 years of essentially unrestrained breeding in a 5000 gallon pond, I didn't ever see the goldfish get to be more than a few dozen full grown adults and a few hundred young of varying sizes. -- derek |

They also eat fry when they can, but the fry are pretty good at hiding in the shallows, among plants etc. -S |

When you think about it fish fry look just like many
insect larvae, about the same size and all and they fish are always nosing around in grasses looking for tasty bits. kathy :-) |
