 Cat-eLog Data Sheet | |
|---|---|
| Scientific Name | Batasio tengana (Hamilton, 1822) |
| Common Name(s) | None |
| Type Locality | Brahmaputra R., Assam, India. |
| Synonym(s) | Gagata tengana, Macrones tengana, Pimelodus tengana |
| Pronunciation | bah tah see oh - ten gan aa |
| Etymology | The genus name comes from the local (Bengali) name of the fish (batasio or batashi). |
| Species Information | |
| Size | 75mm (3") 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 tengana can be distinguished from all congeners except B. pakistanicus and B. spilurus in having a shorter adipose-fin base (14.5–17.5 vs 22.1–35.1% LS) and the presence (v. absence) of a dark mid-dorsal stripe. Batasio tengana appears to reach a smaller size than other congeners (maximum size to c. 55 v. to 101mm LS), except for B. pakistanicus and B. spilurus, which are known to reach 35 and 45mm LS respectively. Batasio tengana differs from B. pakistanicus in the pectoral fin rays not reaching (v. reaching) the pelvic-fin origin, and from B. spilurus in having a longer adipose-fin base (14.5–17.5 vs 12.6–12.8% LS), a deeper caudal peduncle (6.7–8.2 v. 5.7–6.2% LS) a narrower head (12.5–14.5 vs 16.4–16.5% LS), and a more rounded, bulbous snout when viewed laterally. |
| Sexing | Males with a long, slender genital papilla extending to base of second anal-fin ray. |
| Habitat Information | |
| Distribution | Asia: India, Bangladesh, Myanmar and Thailand.
Known from the Ganges and the Brahmaputra River drainages .Batasio tengana is apparently restricted to upper reaches of larger rivers.

| pH | 6.0 - 7.5 |
| Temperature | 23.0-26.0°C or 73.4-78.8°F (Show others within this range) |
| Other Parameters | dH 20. 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. |
| Husbandry Information | |
| 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 | Unreported. |
