No. koi are a peaceful fish but if you have a giant koi that is about 9-20 inches in length then put in a baby goldfish the big koi might mistake the goldfish for flake food or a pellet but its not very common for goldfish or koi to eat other fish!!!!
Yes they would do very well. The problem that occurs in some areas though is that during the wet season flooding they are likely to escape into the waterways and become naturalised ferals and destroy/damage the native habitat and species. That is why Koi are a banned species in Queensland Australia.
It would depend on several factors. First, the outside temperature of the pond. Tropical fish like their water to be in temperatures around 80 degrees Fahrenheit. However, if the fish is large enough or hardy enough, like koi, then it could survive. For certain parts of the year, it may be fine, and for other parts of the year it may not be fine.
Yes, they can but they just need a big tank that's all.
No because some other fish eat different things in a pond.
no
Fish
No, the snail wouldn't eat it because they do not eat other animals, and because he is not fast enough.
Turtles are scavengers and will readily take a bite out of a slow moving Koi trapped in a pond or other confinement.
they eat algae and dead fish
fish and plants because all the animals in the pond or out the pond need to eat fish and plants EASY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
yeah
If the fish are small enough for the snake to eat, yes. Garter snakes will eat small fish.
It depends on what kind of fish it is, and where the pond is. Try worms, all fish eat them, even bass.
Some fish will. It depends which species of fish they are.
No, they do not.
