Platydoras costatus, the Raphael catfish, is a species of thorny catfish native to rivers in Brazil, Suriname and French Guiana.[1] It was long confused with other species in the genus Platydoras, especially the more widespread "true" striped Raphael catfish (P. armatulus).[1] P. costatus grows to a length of 24cm (09inches) SL, and unlike P. armatulus the light stripe along the body of P. costatus does not extend onto the head.[1] [2] This fish is a minor component of local fisheries and is also found in the aquarium trade.
