Every now and then I feed my Zebra Danios and the Angel Fish that they
share a 20 gallon tank with, a wee bit of oatmeal flakes, which they
quickly gobble up. Other than that, I only feed the fish in my care
standard fish food, and occasionally very small crickets [Acheta
domestica] which I raise myself, to my Bettas splendens/Siamese Fighting
fish. ~Dean.
