Ecology of Pethia tiantian
 
Main Ref. Kullander, S.O. and F. Fang, 2005
Remarks The type locality (Nan Hto Chaung) was a small hill stream, about 3 m wide on average, flowing through low forest, with grass and shrub along banks, and over a varied bottom with rock, gravel, and sand. The current was fast, with some riffle stretches. The water level was low, depth mostly less than 50 cm. There was no aquatic vegetation. The water was clear and colorless. Associated fauna included small species of Acanthocobitis (Balitoridae), Barilius, Devario, and Psilorhynchus (Cyprinidae) that were most abundant, but also species of Schistura (Balitoridae), Lepidocephalichthys (Cobitidae), Microrasbora (Cyprinidae), and Mastacembelus (Mastacembelidae), Badis pyema (Badidae), Heteropneustes fossilis (Clariidae), and Batasio tengana (Bagridae) were present. Also fished the larger Ma Kyaww Wa Chaung, into which the Nan Hto flows and samples consist of larger species, predominantly Garra sp. And Amblyceps murraystuarti. A single specimen was obtained from the Mali Hka River, a major river more than 100 m wide, but relatively shallow. Seining along 20 m stonebed shoreline yielded only one P. tiantian, one Acanthocobitis (Balitoridae), and juveniles of several cyprinid species (Banganasp., Neolissochilus sp., Schizothorax sp., Semiplotus cirrhosus, Tor sp.) (Ref. 54351).
