The Thread-finned cichlid is found along mainstream Amazon river in Peru, Colombia, and Brazil, including lower parts of the Putumayo, Trombetas, Negro, and Xingu rivers; lower Tocantins and Capim rivers; Branco river (Amazonas basin) in Brazil and Guyana, and the Essequibo river in Guyana. Males will have an extended dorsal fin and display more coloration. All foods offered will be accepted. Quality flakes and cichlid pellets should provide the staple diet. Supplements of blood worm and brine shrimp should be given on a weekly basis. Include some vegetable matter to bring out the best from these fish. The expected life span for this fish is 6-8 years.
The Thread-finned cichlid is a relatively quiet, peaceful fish which builds a territory. The aquarium should be set up with stones and driftwood. As a result you become caves. However, sufficiently free swimming space should be left. A frequent changing of the water is necessary. Breeding is not too difficult. Some hundreds of eggs are laid in a cave. The female looks after the eggs in the cave, as the male defends the surroundings. After 3 days the eggs hatch and another 3 days later the young are swimming free. Both parents care for the fry. They can be fed on newly hatched brine shrimp initially. The fry are abandoned by their parents at 8-12 mm , but sometimes may continue to stay near the nest and use it for escape in the absence of the parents.

体色成高贵的亮绿色,腹鳍长度会延伸至臀鳍尾端,且雄鱼成长后各鳍都会有明显的延伸。鱼身中央有一明显的黑点,与蓝 宝〈Geophagus jurupari〉是近亲,属半口孵性鱼,繁殖困难,繁殖前会将底沙清除,并将卵产于底床上,卵孵化不久成鱼即会攻击自己的小鱼
