Is it ok to keep stingrays with African cichlids?
No, fresh water stingrays come from a low PH, around the 6.0 -7.0 range. The stingrays that live in the high PH are salt water and either way you don’t have a tank big enough to keep them. Both freshwater and saltwater rays need at least a 200 gallon tank wider than longer and a soft sand or bare bottom. Plus they will eat your fish. Rays are species only fish, not mixers.
