Fish are cannibals

I get questions at my website and occasionally share them here.  Here's one that you may not know or have forgotten:


I have goldfish.

So, do the alive fish eat their dead? I've actually never seen a fish eaten like this is my pond. Sure, I have found plenty over the years, in all seasons, die and float to the surface, but never eaten like this.

I will take your advice and resist the temptation to feed them even in this warm spell.


Yes, all fish will eat other fish. In fact, fish will kill a sick or weak fish. I think it is a way they have of keeping the school hardy.

Your goldfish will be just fine if you never ever, feed them, even in the summer. Just balance the pond ecologically with submerged vegetation and make sure your bioload is not too high and you can just relax and never have to clean fish poop out of your pond except in your yearly cleaning.
