What do gold fishes eat?
They probably eat fish food. Like the ones that you can buy at the pet store that are like flakes or pellets.
Yeah, but you shouldn't feed them that. Betta fish have a high protein diet since they are carnivores. And also goldfish are omnivores, they're supposed to have a high veggie diet. Too much protein for fish can cause bloat, swim bladder problems, and inevitably death. You're better off feeding your goldfish chopped up veggies than betta food.
