Cats, birds, dogs, bears, predatory fish, otters, snakes, frogs, turtles, raccoons, etc. Basically if it can get into a pond that is contained and stocked with fish and has a taste for fish, a pond is a buffet.
Herons love koi fish. So do some cats.
Hungry ones.
Wild koi eat algae.
Nope they sometimes eat there eggs
koi fish would normally eat goldfish food try tetra fin goldfish flakes they are made for goldfish and koi
Yes koi fish can eat bannannas but only in very little pieces. koi fish can actually eat any type of good comon fruit. the only fruit that i know that they can not eat is grape fruit.
Turtles are in fact herbivores and carnivores so they can possibly feed on koi fish
Koi fish is suitable as a feeder fish for other larger fish. If a human wanted to eat a Koi fish, (which in general unlikely), it would be better eaten dead.
yes, depending on its size and the size of the other fish.
dume things
Yes according to my Math book is says Mexicans and Asians eat it around 1:40 a.m. !
If they are bullfrog tadpoles, usually yes
Raccoons are not particular and will eat any fish they can catch, including goldfish and koi from backyard ponds.
Koi are omnivorous and will eat just about any fish that is small enough to fit in their mouths. Koi are essentially pond fish and were bred with broad colourfull backs and grow to over 2 feet long to be viewed from above.
They get along with goldfish but you'll end up with babies that are part goldfish. I have them in the same pond and that's what happened to me. The main problem with putting Koi with other fish, is sometimes the other fish like to eat Koi.
