Relevant Information:

Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal soft rays: 10; Vertebrae: 43. Distinguished from all other Mystus (indeed, from all other Asian Bagridae except Bagrichthys hypselopterus) by its extraordinary high dorsal fin, involving great elongation of the non-serrate dorsal fin spine and first three or four soft rays. Within Mystus sensu stricto, mouth relatively narrow. Occur in medium to large-sized rivers. Adults feed on crustaceans and benthic invertebrates. Oviparous, distinct pairing possibly like other members of the same family. Usually marketed fresh. Aquarium Care: Can only be kept with the same or larger species as this bagrid, common with many from this family, can eat smaller fish. Keep either 3-5 specimens in a large tank with plants to the background. Substrate should be sand and provide hiding places with good filtration. Diet: Tablet and pellet foods. Earthworms, live and frozen foods.
