I have a JD who is about 3" long and he eats a lot. I usually feed him 2 meal worms so that he will be chewing on those while I feed my other fish blood worms. as soon as he is done he comes to the surface and bullies everyone else and eats their food. I am afriad to give him more meal worms cause I dont want to over feed him. He just wont get full like my oscars used to. what should I do?
