Overview
The painted zipper loach is a stone loach for the bottom of a community tank with gentle current. It suits a keeper with a little experience.
Did you know
The zipper in the painted zipper loach's name is the row of stitch-like marks along its back. In this species the stitching is fancy enough that its scientific name means painted or embroidered.
Caring for the painted zipper loach
Keep painted zipper loaches in a group, in a tank of 20 gal (75 L) or more. Give them a varied floor with stones to hop between. In a group they perch on their fins as if on elbows, and they beg like minnows.
Keep the water at 68 to 79°F (20 to 26°C) and a pH of 6.5 to 7.5, with a gentle current. Feed fine sinking foods.
Zipper loaches sit at the friendly end of the stone loach spectrum. The painted zipper loach is mostly peaceful and safe with community fish, so keep it with gentle company.
Good to know

In the wild
The painted zipper loach comes from the Ataran drainage, on the border of Myanmar and Thailand. It lives in clear streams over sand and gravel.
