Apistogramma cacatuoides is one of the few dwarf cichlids from South America than does well in basic, harder water. It's natural habit is the Rio Ucayali basin in Peru, in waters that have a pH between 7 and 8 with a moderate hardness of 12 dGH. An easy spawner if conditioned with good food and in a relaxed aquarium environment. Standing branches and floating plants will help to calm the fish, and dither fish should be present. [Dither fish are small fish like shoaling tetras that suit the same water parameters and will also provide a sense of security for the cichlids which otherwise could be shy and retiring.]
Males reach 8 cm (just over 3 inches), females 5 cm (2 inches). The attached photo is the Triple Red male. "Red" can mean many things from reddish-orange to red. Colours may be dependent on the locality of the fish, and can also be contingent on foods, so a good diet of nourishing prepared foods and frozen will probably help.
