Overview
The yoyo loach is a hardy, patterned loach that lives on the bottom of a community tank. It is a step up from the easiest fish.
Did you know
The yoyo loach owes its name to the dark markings on young fish. They often line up to read like the letters Y-O-Y-O along the flank. The pattern is clearest in juveniles and dissolves into a maze of fine lines as the loach matures.
Caring for the yoyo loach
Keep yoyo loaches in a group of six or more, in a tank of at least 42 gal (160 L). Give them a soft sand substrate, with smooth rocks and driftwood built into plenty of caves and gaps. Shaded retreats let the group forage in the open with confidence.
Keep the water clean and stable, at 66 to 81°F (19 to 27°C) and a pH of 6.0 to 7.5. Brisk, well oxygenated flow suits a fish from cool, flowing hill streams.
Feed sinking pellets, frozen bloodworms, snails and the occasional vegetable. They dig through sand and explore wood and rock for food, and they are reliable hunters of pest snails.
In a good-sized group they form an active shoal and become relaxed and outgoing. Kept in ones and twos, they can turn nippy. They are peaceful otherwise, so pair them with active, similarly robust community fish. Breeding has not been recorded in home aquariums.
Good to know
The yoyo loach, Botia almorhae, is a member of the family Botiidae. Its dark pattern sits on a silvery-gold body. Like other botiine loaches, it has a sharp spine below each eye that it can raise in defense. The spine catches easily in a net. Commercial fish are farmed, often with hormone induction, so few are collected from the wild.
In the wild
The yoyo loach comes from northern India, Nepal and Bangladesh. It lives in the clear hill streams and rivers of the Ganges drainage, over sand, gravel and stone. These waters shift with the seasons.
