Yoyo Loach

About

The yoyo loach (Botia almorhae) gets its common name from a neat trick of pattern recognition: juveniles display alternating 'Y' and 'I' shaped bars along their sides that, if you look at them just right, spell out 'yo-yo'. As fish age, those bars gradually break up and merge into a more irregular arrangement of spots and reticulations on a pale yellowish or silvery body. Wild fish come from hill streams in northern India and Nepal, often at elevation, favoring rocky and gravelly stretches of fast-moving water. In the aquarium they're energetic, bottom-oriented fish that spend a lot of time rooting around for food, but they also venture into midwater and will occasionally grab something at the surface. They're gregarious and need to be kept in groups of at least five or six, ideally more, because solitary individuals tend to become withdrawn or take their frustrations out on tankmates. Even in a group there's a clear social hierarchy, and newcomers can trigger extended dominance displays. Long-finned, slow-moving fish are not good companions; fin nipping is a real risk. One charming quirk is their habit of producing audible clicking sounds when excited, and they'll sometimes settle sideways or nearly vertical against decor, which looks alarming but is perfectly normal resting behavior. A rewarding species for intermediate keepers who plan their community carefully.
