Relevant Information:

Dorsal soft rays (total): 7; Anal soft rays: 5. Anal fin with 4 branched rays; dorsal surface of body and head covered by distinct black dots; low caudal peduncle 9.7-11.3% SL; 94-120 teeth in each dentary. Mature males possess the remarkable morphological modifications already known to occur in other Pareiorhaphis species, a skin fold on the dorsal surface of the unbranched pelvic-fin ray, a thickened pectoral-fin spine, fleshy lobes on the lateral margins of head, and hypertrophied odontodes emerging from those fleshy lobes and on the pectoral-fin rays. When compared to males, females posses an enlarged, swollen urogenital opening, while males have a small and pointed urogenital papilla. Aquarium Care: Will need a good water flow in the aquarium as found under rocks in fast flowing waters.
