I have a 260 L tank and have to rainbow sharks with 12 assorted cichlids and have not had any issues.
sharks
no because the bigger cichlids will eat the little cichlids.
It is expected that Jewel Cichlids with Convict Cichlids.
Tiger barbs, many cichlids, some gouramis, sharks, and eels can all be put together in the same tank as long as the is big enough to hold them all.
Mystery snail (Pomacea Bridgesii) also called Apple snail are OK with the smaller fish but to put them in with large and aggressive cichlids like the Jack Dempsey (Cichlasoma octofasciatum) is begging to have them killed and eaten. The simple answer is no they are not compatible.
Anything carnivorous and big enough will eat them. Think Oscar.
Cynotilapia cichlids and kribensis cichlids belong to different genera and have significant differences in their breeding behaviors, habitats, and genetic makeup. As a result, they are generally not compatible for crossbreeding. While some cichlid species can hybridize, it is unlikely that these two would successfully produce viable offspring. Therefore, breeding between Cynotilapia and kribensis is not feasible.
No they can not.
It's easier to say they are good community fish that are compatible with most normal tropical fish. They are not compatible with fish that need special water conditions like Discus or African Cichlids. They are also not suitable to be mixed with large predators like Oscars or Arowanas who would hunt and eat them.
Would what get along with African Cichlids?
Eels find them very delightful. Most predator type fish, like stingrays, trigger fish, sharks, larger cichlids and other crayfish.
