Metahomaloptera longicauda, a member of the family Balitoridae, comes from southern Chinese mountain streams, where it inhabits fast-flowing mountain streams, clinging to rocks. Peaceful grazer; squabbles are brief pushes and algae and biofilm specialist; supplement with wafers, it grows to 4.5–6.6 cm and adapts well to a properly set-up aquarium in the 18–26 °C range. Other Metahomaloptera species in our database include Metahomaloptera omeiensis.
