If you’re a fan of the eartheater cichlids from South America, then you’ll be happy to know a new species was recently described. Gymnogeophagus jaryi is found in the southern tributaries of the Middle Paraná basin of Argentina (on the border with Paraguay). The standard lengths (SL) for the male holotype and female paratype are 113.1 mm (4.5″) and 73.3 mm (2.9″), respectively.
This is a beautiful little fish with a nice nuchal hump and light blue coloration on the adult males. You can find a more thorough description, including multiple photos, in the PLOS One journal article where it was described. A shout out to Amazonas Magazine, which has a nice, short write up about the fish.
