Green Snook Cichlid (Petenia splendida)


The Green Snook Cichlid, scientifically known as Petenia splendida, is a striking species native to Mexico and northern Central America. Reaching lengths of up to 45cm in the wild, specimens kept in aquariums typically grow to around 30cm. Adaptable to various water conditions, they thrive best in slightly alkaline water with a pH range of 7.0-7.5 and a general hardness (GH) of more than 15.

One of the most remarkable features of the Green Snook Cichlid is its transformation in coloration as it matures. While fry exhibit a typical black and silver pattern, adults of the red form display a spectacular solid red coloration. Initially showing a pinkish or mottled coloration, this intensifies with size and age, eventually developing into the rich, rosy red color seen in adults. Feeding them foods rich in carotene, such as krill, helps accentuate their vibrant red coloration.

In terms of size, males tend to grow larger than females, with males reaching sizes of up to 35cm and females typically growing to at least a foot in length. While sexual dimorphism is not obvious, males often exhibit a higher number of highlighted scales and greater color intensity compared to females. Additionally, males may have more pronounced pearly outlines on their scales.

Green Snook Cichlids are omnivorous and accept a variety of meaty frozen foods and pellets. They are an attractive addition to community tanks of large cichlids with similar temperaments, showcasing their showy coloration and striking appearance.
