Botia (Indian loaches) is a genus of freshwater fish in the loach family (Botiidae). It was a large genus with about 20 species.
Loaches are a fun addition to any tropical freshwater aquarium. Generally, they are peaceful scavengers that spend their time rooting about for tidbits of food on the bottom. Many loach species actually prefer to be kept in schools, and some species will literally pine away with loneliness if kept alone.
