I fed my ADF's frozen bloodworms[of course, I thawed them first] but I think the prefer small live foods. Black worms work great for them. My ACF didn't care about what he got as long as he ate...lol
If I ever get cichlids I'll probably make a feeder tank. Get me some fast breeding fish and feed them that. It'd work, right? It'd save me the problem of keeping stuff special and save money to boot.
