Schistura aizawlensis

Overview

A stream loach with a narrow known range, Schistura aizawlensis develops five to seven broad flank bars and an orange patch before the tail base. Clean, oxygen-rich water and a network of rock and wood retreats are central to its care.

Distribution & habitat

It is known only from the Muthi near Aizawl in Mizoram, India. The Muthi feeds the Tuirial and then the Barak–Surma–Meghna system. Collection habitat is a moderately to strongly flowing stream over gravel and rocks.

Aquarium setup

Create a stream-style arrangement from mixed rocks, sand, fine gravel, and worn boulders. Branches add shade, crevices, and broken sight lines. Robust attached plants are more suitable than delicate vegetation.

Torrent conditions are unnecessary, but high oxygen and some movement are important. Use filtration, circulation, or aeration as needed. Prevent organic waste accumulation through routine weekly water changes of roughly 30–50%.

Diet & feeding

It likely takes mostly small insects, worms, crustaceans, and other tiny animals, with limited plant matter or detritus. Suitable dry food is accepted, but daily small live or frozen meals should supplement it.

Sexual dimorphism

Males possess a prominent flap beneath the eye, which females lack.

Breeding

Reproduction is unrecorded.

Notes

The bars extend below the lateral line, with orange usually strongest on the upper tail base. Adult pattern and the suborbital structure are useful to assess together during identification.
