my BGK will eat enything that floats in the top right corner of my tank. Him and by bichir have figured out that this is where floating food accumulates and dart to this corner as soon as I open the lid of my tank. He eats freeze dried bloodworms and mysis shrimp, floating pellets, flake. When I add forzen bloddworms he goes bonkers for it and will hit it violently and shake it like a shark.
