|Cat-eLog Data Sheet|
|Scientific Name||Batasio fasciolatus Ng, 2006|
|Type Locality||Market at Malbazar, 26°32'30"N, 88°44'17"E, West Bengal, India.|
|Pronunciation||bah tah see oh - faa see oh late us|
|Etymology||The genus name comes from the local (Bengali) name of the fish (batasio or batashi). From the Latin fasciolatus, the diminutive form of fascia, meaning belt, in reference to the banded pattern of this species.|
|Size||71mm or 2.8" 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 fasciolatus n. sp. can be distinguished from all congeners except B. tigrinus by the adult colouration of five to six vertical dark brown bars on a light brown body (vs two or less vertical bars, uniform colouration or only horizontal marks). It differs from B. tigrinus in having longer dorsal spines (13.6–16.8 vs 9.4–12.5% LS) and pectoral spines (12. 7–14.3 vs 10.3–12.9% LS)and smaller eye [16.5–18.8 vs 20.3–24.8% head length (LH)]. Specimens of Batasio fasciolatus n. sp. were previously identified as B. tengana, but can be further distinguished from it in having a longer adipose-fin base (24.5–25.3 vs 14.5–17.5% LS), deeper caudal peduncle (10.1– 11.8 vs 6.7–8.2% LS) and smaller eye (16.5–18.8 vs 21.9–32.1% LH). The only other species of Batasio with at least one vertical bar on the body found in the Brahmaputra River drainage is B. merianiensis, but B.fasciolatus differs from it in having smaller pectoral spine (12.7–14 .3 vs 16.3% LS) and eye (16.5–18.8 vs 25.9% LH).

|IUCN Red List Status||Least Concern|
|Temperature||20.5-25.0°C or 68.9-77°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.|
