African Cichlids are 75% vegetarians and 25% meat. They are famous for getting bloat if fed to much protein. Vegetable acts like a laxative for them.
I feed Omega one Veggie pellots, Hikari frozen vegtable matter, Omega one seaweed, Massivore Pellots (Grow very fast on these) Omega one sinking color pellots and cucumbers. Not all of them every day, but mix them up.
Also if you get bloat (WC Fronts are famous for it, if they are brought up to the surface to quickly) Stop all meat food and feed Vegtable food for at least a week and 9 times out of 10 will correct the problem.
