I have a young male dovii that is 3" long. He eats Ken's Basic Growth Flake (47% protein) with vigor. He also likes frozen mysis shrimp and bloodworms on occaision. I'd like to give him more variety of foods without starving him into accepting them. He will eat no other dry food, flake or pelleted, other than the growth flake. I'm thinking of giving him more commercial frozen foods, specifically beefheart, krill, clams, and other foods in addition to the mysis and bloodworms he eats. He will still get the flake food too. I'll probably only feed him beefheart once or twice a week. What do you all think? What has worked for you?
