yes, they are scavengers and will eat almost anything.
your cat If in an outside pond, it isn't unusual for a Heron to take them.
Four carnivores in a pond are seagulls, frogs (eat insects), herons, and alligators (none of these are usually in the same pond, with the exception of seagulls and frogs).
The goldfish will eat the mosquito's larvae before they can leave the pond and fly.
not if it is your pet. you have to go to the oet store for certain pet food for goldfish
Yes they do. There was a 100 in my pond, now they are less than 20! My son-in-law nearly had his ear off as the gull flew down past his face, caught the fish in his claws and flew off!!
Most likely not. If there are goldfish, then there are definetely going to be predators. Goldfish are small, and one predator could eat about 5 goldfish. It's very unlikely, but possible.
Goldfish will start to eat their eggs once they have finished spawning them. They do not look after their eggs at all.
who cares? I think they will eat them because i once had two little guppies and the next morning they were gone. Answer- Yes, they will eat them. If they don't the guppies will die, because the stuff on the goldfish is like a poison for other fish. You should only put goldfish with goldfish.
When the crayfish ages, it has a chance of chopping your goldfish to pieces, and possibly eat it.
They should be provided with goldfish or pond food instead
Seagulls will eat about anything
Big fish do not eat seagulls. Although, whales and porpoises do, in fact, eat seagulls from the ocean surface.
