Ladder Loach

About

The ladder loach (Botia rostrata) is a fair bit more interesting than its modest profile might suggest. Worth noting upfront: nearly all fish sold under this name in the hobby are actually B. sp. 'upper Brahmaputra', a closely related but taxonomically distinct form. True B. rostrata sensu stricto almost never appears in the trade. Whatever form you're keeping, expect a fish with a pale to golden base body color patterned with 9-10 dark vertical bars that tend to merge and blur with age, particularly toward the front of the body. Adults often develop warm orange or gold tones on the snout and lower fins. In the wild, these fish inhabit both fast-moving hill streams and larger mainstream rivers across northern India and neighboring regions, where they root around for insect larvae and other small invertebrates. In the aquarium they're peaceful enough, but their social needs deserve serious attention. They need to be kept in groups of at least five or six, and ideally ten or more. A lone specimen or a small trio can become withdrawn or confrontational, and dominant individuals may bully subordinates to the point of preventing them from feeding. Watch for fascinating group behaviors like synchronized shadowing and audible clicking. Fin-nipping is a risk with slow, long-finned tankmates, so choose companions carefully.
