Schistura geisleri is a species of ray-finned fish in the genus Schistura , the most speciose of the genera within the stone loach family, Nemacheilidae. Its known range is in the upper parts of the Chao Praya in Thailand but it has also been reported from the Tapi River in Peninsular Thailand, as it has not been recorded from the darainages between these two systems the taxonomic status of the Tapi population may need to be reassessed. [1] Its habitat is slow flowing streams with depths no greater than 30 cm during the dry season and in shallow riffles with a substrate consisting of pebbles which are up to 5 cm in diameter, with a moderate current and clear water. [2] The specific name honours the German aquarist Rolf Geisler (1925-2012), in thanks for his "valuable help". [3]

Schistura oedipus is a species of troglobitic stone loach endemic to caves in the Pang Mapha karst formation in Mae Hongson Province in Thailand. It is only found in very fast flowing cave streams where it feeds on micro-organism and organic matter. This species is highly sensitive to disturbance, changes in water quality and hydrography. The specific name oedipus refers to the mythical Ancient Greek king of Thebes, Oedipus who tore out his own eyes, this species has degenerate eyes.
