I've had my ghost knife only about 2 months now and he eats alot. I feed him mostly bloodworms. What else can he eat besides that? Everything else I put in there he doesn't mess with it
They need a little time to get used to new food and of course bloodworms are a favorite of thiers... Our's eats a variaty of foods now..frozen krill....and seems to love a new frozen mix I came up with for the smaller fish.
