Overview

The ornate stone loach is a compact, mostly peaceful bottom loach for a warm river community tank. It is a fish of moderate difficulty.

Did you know

The ornate stone loach's name means adorned, yet ornate is a relative term among stone loaches. Its bars break up and wobble, and its markings are edged rather than simple. Most of its genus wears a set of tidy straight stripes as the usual uniform.

Caring for the ornate stone loach

Give a small foraging group of ornate stone loaches a warm tank of 20 gal (75 L) or more. Lay a floor with structure, mixed sand and gravel divided into patches by rounded stones for cover. They settle into a layout like this without much squabbling.

Keep the water warm and moving, at 72 to 79°F (22 to 26°C) and a pH of 6.5 to 7.5. As a stream fish, it prefers clean, oxygen-rich water, so run steady filtration with a gentle to moderate current.

The ornate stone loach forages over the bottom. Feed fine sinking foods, frozen daphnia and small bloodworm that reach the substrate. It is mostly peaceful, so pair it with calm, current-tolerant midwater fish. Its aquarium breeding is not on record.

Good to know

Nemacheilus ornatus was described by Maurice Kottelat in 1990. It belongs to the family Nemacheilidae.

In the wild

The ornate stone loach is known from the Mae Khlong basin in western Thailand. It lives in flowing water over gravel and sand.
