Overview
The giant kuhli loach is a sand-burrowing kuhli for the bottom of a community tank. It is easy to care for.
Did you know
The giant kuhli loach can gulp air at the surface and absorb oxygen through its gut. That ability is an adaptation to the low-oxygen, seasonally stagnant waters it inhabits.
Caring for the giant kuhli loach
Keep giant kuhli loaches in a tank of 20 gal (75 L) or more with a soft sand bed. They are nocturnal burrowers, so give them plenty of shaded cover such as wood, leaf litter and plants. Fit a tight lid, because kuhli loaches are escape artists that can slip out of surprisingly small gaps.
Keep the water at 72 to 82°F (22 to 28°C), with a pH of 5.5 to 7.0. The giant kuhli loach roots through the substrate for worms and insect larvae. Feed sinking foods, frozen bloodworm, tubifex and brine shrimp.
Keep at least five or six together, since it is far more confident and active in a group. It is peaceful and community safe, and it suits tanks with gouramis, rasboras, barbs and other calm fish. Very small shrimp fry may be eaten.
Good to know
The giant kuhli loach is a true loach in the family Cobitidae and was once placed in the genus Acanthophthalmus. It is the heaviest-bodied of the banded kuhli loaches, with broad dark saddles over a pinkish base.
In the wild
The giant kuhli loach is found in Thailand, Cambodia and the lower Mekong basin. It lives in slow streams and floodplains with a soft bottom and leaf litter.
