It sounds like the fish have bloat. You have mbuna? If so that hikari is probably too high in protein which could be causing the bloat. You need to try and find someplace that sells metronidazole or jungle parasite clear. By this point it may be too late, but it would be a good idea to treat the rest of the tank to help prevent anyone else from getting sick.
You could buy an API Freshwater Master Test Kit.
