aquaponics fish speciesThe goldfish is a small member of the carp family. They’re one of the earliest fishes to be domesticated and perhaps the most popular aquarium fish. In the wild, they eat crustaceans, insects, and various plant matter.
If overfed, they produce more waste, which makes them good for aquaponics. However, because of their small size, lack of protein and susceptibility to parasites, goldfishes are not recommended for eating.
