Crenicichla monicae

Crenicichla monicae is a species of cichlid native to South America. It is found in the lower Rio Uaupés and lower Rio Içana, tributaries of the upper Rio Negro in Brazil. This species reaches a length of 27.3 cm.

The fish is named in honor of ichthyologist Mônica Toledo-Piza Ragazzo, whose efforts in publishing, in 2002, Alfred Russel Wallace’s drawings from his 1850-1852 expedition to the Rio Negro and Rio Uaupés region, were a great service to science, and also decisive for identifying this fish as a new species.
