|Type Locality||Lam Chi, 1.5 kilometers below highway 23 bridge, 4 kilometers west of Selaphum, Roi Et Province, Thailand.|
|Pronunciation||bag RICK thiss - orb skew russ|
|Etymology||Bagrichthys: From bagrus, the name of a catfish genus frequently used to form generic names, and the Greek ichthys, meaning fish. From the Latin obscurus, meaning indistinct, in reference to the lack of pale patches on this species.|
|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.|
|Distribution||Asia: Chao Phraya, Bang Pakong and Mekong drainages in Indochina.

|IUCN Red List Category||Least Concern, range map and more is available on the IUCN species page. Last assessed 2011.|
|pH||5.4 - 7.0|
|Temperature||22.0-28.0°C or 71.6-82.4°F (Show species within this range)|
|Feeding||Readily accepts prepared foods. Frozen brineshrimp appears to produce the most activity from the fish and frozen bloodworm is also relished.|
|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.|
