|Cat-eLog Data Sheet|
|Scientific Name||Batasio spilurus Ng, 2006|
|Type Locality||India: Assam, Dibrugarh district|
|Pronunciation||bah tah see oh - spy lure us|
|Etymology||The genus name comes from the local (Bengali) name of the fish (batasio or batashi). From the Greek spilos, meaning spot, and ouros, meaning tail, in reference to the distinct spot at the base of the caudal peduncle.|
|Size||55mm or 2.2" SL. Find near, nearer or same sized spp.|
|Identification||The bagrid genus Batasio Blyth comprises of small, laterally compressed catfishes distributed in South and Southeast Asia, diagnosed from its confamilials in having large sensory pores on the head, a narrow mental region, a pair of posteriorly-directed processes on the anterior part of vomer, a transversely-elongated bar-like entopterygoid, and the metapterygoid in close contact with the quadrate but free from the hyomandibular (Mo, 1991).
Batasio spilurus n. sp. can be distinguished from all congeners in having a short adipose-fin base (12.6–12.8 vs 14.5–33.3% LS) and more slender caudal peduncle (5.7–6.2 vs 6.7–11.8% LS). It further differs from all congeners except B. pakistanicus and B. tengana in having a slender body (12.6–13.6 vs 15.8–23.9% LS). It can be further distinguished from B. pakistanicus in the pectoral fin rays not reaching (v. reaching) the pelvic-fin origin, and from B. tengana in having a wider head (16.4–16.5 vs 12. 5–14.5% LH), the presence of a distinct black triangular spot at the base of the caudal peduncle (vs spot very diffuse or absent), and a sharper snout when viewed laterally.
|Distribution||Known from the Brahmaputra River drainage in the vicinity of Dibrugarh and in the Siang River in Arunachal Pradesh.

|IUCN Red List Status||Data Deficient|
|Temperature||20.0-25.0°C or 68-77°F (Show species within this range)|
|Other Parameters||The water should be cool and heavily oxygenated with a good flow as these fish occur in hill streams.Anything above 25 C will hamper long term survival as these fish tend to burn away at higher temperatures.|
|Feeding||Is known to take processed food but prefers live food like blood worms, frozen brine shrimp etc. Needs sometime to gradually get weaned off live foods. Spot feeding will help in case tank mates are voracious feeders.|
|Furniture||Fine sand for the bottom and smooth pebbles / rocks. Cover / hiding spots can be created with either plants or wood.|
|Compatibility||A peaceful species suitable for a hillstream biotope.|
|Suggested Tankmates||Peaceful Cyprinids like Puntius or Oreichthys and Balitorine loaches like Schistura or Nemacheilus species.|
|Breeding Reports||There is no breeding report.|
