Species Information
Size	249mm or 9.8" SL. Find near, nearer or same sized spp.
Identification	Members of the highly specialized and unusually-shaped bagrid catfish genus Bagrichthys Bleeker, 1858, live in large muddy rivers throughout Southeast Asia and are characterised by their elongate and laterally compressed caudal peduncle, the dorsally-directed serrations on the posterior edge of the dorsal-fin spine, gill membranes united but free from the isthmus, and a long adipose fin without a free posterior margin (Roberts, 1989). A relatively small and narrow mouth opening; extremely reduced oral dentition; relatively short dorsal-fin spine with 15 or fewer serrae; both inner and outer mandibular barbels crenulated; a slender body (body depth at anus 15.1-18.4% SL; depth of caudal peduncle 6.7-8.3% SL); a short adipose fin base (length 43.3-48.9% SL); the genital papilla in males touching the base of the first anal-fin ray; a uniformly brown body without both a pale midlateral stripe and pale blotches on the sides of the body.
Sexing	Males have a prominent genital papilla in front of the anal fin and longer barbels.
General Remarks	Occurs in large muddy rivers. Feeds on small fishes, benthic invertebrates and large amounts of plant detritus.

pH	5.4 - 7.0
Temperature	22.0-28.0°C or 71.6-82.4°F (Show species within this range)
Husbandry Information
Feeding	Readily accepts prepared foods. Frozen brineshrimp appears to produce the most activity from the fish and frozen bloodworm is also relished. User data.
Furniture	The fish loves tangles of plants which it carefully inspects for morsels of food after lights out. A suitably sized pipe or cave is required for this fish as it can quite easily damage itself in panic if this is not provided and easily accessed by the fish. Heater elements should be guarded or positioned so that they are not used for refuge - this fish is prone to heater burns.
Compatibility	A timid fish that does well in a sizeable aquarium inhabited by smaller fish. Although a night-time prowler, even small fish are safe enough. Conspecifics may be aggressively territorial.
Breeding	Not reported. Spawns at the beginning of the rainy season and utilizes the flooded forests along the river edge. Juveniles appear in August.
Breeding Reports	There is no breeding report.
