Hi. Some of my Malawi species were susceptible to bloat (Ps. elongatus Chewere) so I feed only spirulina. Those were the only ones I had trouble with. I keep mainly Malawi Mbuna, also I have Lithobates. Is there a decent flake that I will interest my Malawi Mbuna besides spirulina that will not give them bloat. I started feeding them Spirulina with Garlic but some of the more timid eaters are still not getting enough. Are brone shrimp or earthworm flake probably too risky for Malawi Cichids?
