Try feeding your armatus cichlids. Much better quality and healthier than guppies and comets. Convixts and african rifts are very easy to breed.
Temp - Stays around 76 to 78 degrees.
I am also curious to find out if feeding live food like gold fish is better in the long run for them as appose to feeding them dead fish. I would also want to know does feeding them salt water fish have any adverse effects on their health. Should you only feed them freshwater fish?
Breeding convicts actually sounds like a good idea. I never thought about doing that.
