What other cichlids do you have aside from your Midas? Varied diet is always important. Bloodworms, veggies, earthworms, mosquito larva, brine shrimps and a few others add to their diet.
I change between spirulina, tetra cichlid crisps and the tetra color granuals. This with occasional live brine shrimp, blood worms and krill helps me vary their diet.
My fish are pigs any ways, as soon as I open the top lid I get splashed in the face!
