If the toads are small enough they certainly will eat them and the tadpoles too. If the toads are toxic as is the case with cane toads the goldfish/koi will be poisoned and may well die.
koi fish would normally eat goldfish food try tetra fin goldfish flakes they are made for goldfish and koi
Yes they do.
If the Koi is large enough it may well eat a goldfish fry but Goldfish and Koi are not fighting type fish so they do not normally bite one another.
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.
Only Carps eat duckweed, such as Goldfish and Koi. Danios do not. Hope that helped. :)
Raccoons are not particular and will eat any fish they can catch, including goldfish and koi from backyard ponds.
Yes pond comets and other pond goldfish get along with koi, however koi can get over 24 inches long when a comet typically doesn't grow more than 12 inches- that's quite a considerable difference in size (which is why its often best to keep koi with other koi and goldfish with other goldfish).
I think it's KOI I have a friend who's is a really big koi lover. He is very adamant about the fact that koi are not goldfish!
They will eat many plants. They are very fond of Elodia densa and Elodia stricta.
Koi is a type of fish. Just don't put koi in the pond and it will not be a koi pond.
Goldfish do not have hair; instead, they have scales that cover their bodies which can vary in type and colour depending on which type of goldfish you have.
No they are not goldfish
