Relevant Information:

Description: Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal soft rays: 12 - 15; Vertebrae: 41 - 43. A primitive catfish family from the rivers of Chile and Argentina so would therefore be considered cool water catfishes. Very rarely seen in the trade so there is not much information on keeping the 6 known species in the Diplomystes genera. Arratia (1987) erected the genus Olivaichthys for the Argentinian specimens but some authors still treat Olivaichthys as a synonym of Diplomystes. Remarks: Diplomystes chilensis is a component of local commercial fisheries as well as being a gamefish.
