Tuirial

The Bengal danio, Devario devario, is a devario from the Ganges and Brahmaputra river systems in northern India, Nepal and Bangladesh. Also known as the 'Sind danio', it is told apart from congeners by a single, interrupted lateral stripe on each flank. It is relatively common in the trade and produced commercially, with an albino form and a short-bodied variant sometimes sold as D. sp. 'mini Putao'.

Schistura aizawlensis is a nemacheilid loach known only from the Muthi River, a tributary of the Tuirial in Mizoram state, India. It has been collected for the aquarium hobby under an unknown trade name. Adults have 5-7 broad vertical bars on the flanks and an orange patch before the caudal-fin base. The type series came from a moderate to strongly-flowing stream with a substrate of gravel and rocks.
