A.Centrarchus male in normal colouration I’m ashamed to say that Archocentrus centrarchus has been a rather overlooked species in my time of keeping Central American cichlids, but after acquir- ing a small group back in 2011, I’m certainly glad I took the plunge. Archocentrus centrarchus hail from the Atlantic slope of Nicaragua and Costa Rica, inhabiting the quieter parts of rivers and streams, they are also found in lakes (Lake Nicaragua). They are classed as a small to medium sized cichlids where certain aquarium populations are reported to attain sizes of up to 20cm/ 8”, however, sizes of 15cm/ 6” is usually the norm. All currently assigned species of Archocentrus are substrate spawners. The etymology means archo = anus + Greek, kentron = stinger; referring to the spine on the anal fin, centrarchus = this name was given to the species because of similarity in ap- pearance to the flier sunfish of the genus Centrar- chus. Younger specimens are a silvery grey colour with around seven vertical bars. As they mature the overall body colour will take on a yellow/green complex with light blue extending from the gill cover through the middle of the flanks. Sexual di- morphism can be weak with centrarchus, but as the fish mature the male will become more heavily built with a pointed dorsal fin, females appear more rounded in comparison. Although described by Gill and Bransford in 1877, the fish weren’t commercially available in the aquarium trade until specimens were imported in 6
