Hello mfk. I recently bought a silver arowana from gunpowderaquatics and he came in the mail on December 28th. I figure that he was just nervous the first few days but he still hasn't ate anything. I've tried massivore bloodworms brine shrimp hikari cichlid bio gold hikari food sticks and countless other things including beef heart and crickets. Idk what to feed him. The guy I bought him from said he fed the tank a pellet and bloodworms so idk why he isn't eating. Any help from other silver arowana owners would be great thanks.
