Icthyologists from Argentina in conjunction with scientists from the Czech Republic have finally unveiled a new species of pike cichlid which makes its home in the Parana River drainage of Argentina.

This new cichlid was dubbed Crenicichla hu in a recently published paper in the journal Zootaxa. The lead author, Lubomir Pialek along with coauthors have distinguished this new cichlid from similar species in the area as they have a combination of dark gray or dark brown to black color body and fins, 7 to 9 black spots on their flanks, 47 to 54 scales in row E1, and the dorsal fin on the adult female species has a pattern of black and white horizontal stripes or blotches.

This new species of cichlid has formally been confirmed and recognized by a phylogenetic study which was carried out in the same paper by using the mitochondrial ND2 gene.

The cichlid was scooped up from a swiftly running, clear stream with a substrate mud, stone and sand. Its name, Crenichlia hu, comes from the Guarani word for black (hu), referring to its dark coloring.
