Species Information
Size	12mm or 0.5" SL. Find near, nearer or same sized spp.
Identification	Species of the neotropical family Scoloplacidae are distinguished from other Siluriformes by the presence of a conspicuous shield-shaped rostral plate bearing numerous large and recurved odontodes. Scoloplacidae is a monogeneric family endemic to South America and known from the Amazon, Paraguay, and Parana basins. The worlds smallest known catfish are from this genus, the smallest is most likely S. dolicholophia. Body color dark brown. Head and cheek region uniformly dark brown. Minute to moderately sized dark brown chromatophores diffusely scattered over dorsal surfaces of trunk.Trunk with four dark brown pigment saddles. Sides of trunk with red midlateral pigments from middle of pectoral fin in specimens from Rio Unini.
Sexing	The males only grow up to 15 mm TL, the females can grow a little bit bigger and become clearly thicker.
General Remarks	Within the aquarium trade, this group of fishes has been almost totally unknown. Perhaps single specimens are sometimes imported together with other fishes (for example cardinal tetras). The tiny adult size and secretive nature of these fishes are to blame for their relative obscurity.
