Acarichthys heckelii is an elegant South American cichlid recognized for its elongated body and long, flowing fins that create a graceful appearance in large freshwater aquariums. Its natural coloration ranges from silver to olive with subtle markings, giving it a classic and refined look.

This species is relatively peaceful compared to many large cichlids and can be kept with other calm, similarly sized fish. Acarichthys heckelii thrives in spacious aquariums with sandy substrate, strong filtration, and stable water conditions.
