I've just recently purchased a bunch of fish and I'm trying to find the right food to feed them. I've got 4 apistogrammas, 2 german blue rams, 3 discus, 5 glowlight tetras and 4 corys. I am feeding them sinking cichlid pellets, frozen dried blood worms and tropical flakes. The discus are not eating enough and neither is the german ram. Food suggestions?
