Schistura pridii · Mini Dragon Loach

Overview

Small and yellow with four dark bars, Schistura pridii often shows saddle-shaped markings containing rounded yellow centers. It requires clean, oxygen-rich stream conditions and suits a species setup or gentle small companions rather than competition with territorial bottom dwellers.

Distribution & habitat

It is endemic to a handful of upper Chao Phraya tributaries in northern Thailand, with most known populations in Doi Chiang Dao Wildlife Sanctuary. Shallow forest hill streams around a thousand meters elevation run over gravel, rocks, and boulders, with strong seasonal variation in flow.

Aquarium setup

Use sand, fine gravel, mixed rocks, and boulders, adding branches for shade, crevices, and broken sight lines. Robust attached plants can grow on the structure.

Maintain clean water with weekly changes of roughly 30–50%, preventing organic waste buildup. High oxygen and some flow are important without reproducing peak seasonal torrents throughout the aquarium.

Diet & feeding

Naturally a micropredator, it takes tiny insects, worms, crustaceans, and other small animals, with only minor plant matter or detritus. Captive feeding is usually straightforward using suitable dry foods alongside daily small live or frozen meals; chop larger bloodworms.

Behaviour & compatibility

A species setup or similarly small peaceful open-water companions is preferable. Avoid territorial or strongly competitive bottom dwellers. Although not a tightly schooling fish, it seems to benefit from conspecific company, with limited aggression where cover is abundant.

Sexual dimorphism

No clear sexual differences are confirmed. Gravid females may look fuller, which remains a tentative clue.

Breeding

Captive reproduction is unreported.

Notes

Grazing, deforestation, deliberately set fires, and aquarium collection put pressure on its limited habitats. Occasional trade availability does not establish abundant wild stocks.
