Fish are cannibals

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

Koi and Goldfish eat their babies

Question I received lately: I have Koi and Goldfish. I feed them daily. Why don't I have babies?



Pondladay sez: Chances are the fish are eating their babies. They are not good parents.
You must feed koi. Goldfish can exist and live well eating off the plants in the pond....unless you have koi who will eat them all.

The more you feed them, the bigger they get and the hungrier they get. Sooner or later your bio-load will be too heavy and your biggest fish will die, but in the meantime, your fish will eat every baby they catch.

My goldfish turned brown, help!

Most goldfish are born black/brownish. That 's because their mommas will eat them if they can find them, so being in camouflage is a survival tool. Most of the fry turn orange/yellow, but some stay black/brown. When you see tanks and tanks of gold goldfish in the store you are seeing them with the dark ones culled out.

After your fish spawn for a few years, you may find that the surviving babies, now grown up, are black/brownish, so,you may want to start over again. But, if you have named your babies and have become best buddies, and want to stay in contact, give them to a friend or relative.
