Sinogastromyzon wui
Butterfly Loach, Hong Kong Pleco
Sinogastromyzon wui is a rheophilic loach adapted to living in fast-flowing waters. Its flattened body structure allows it to cling onto rocks in strong currents, making it an ideal choice for riverine setups. Its behavior is non-aggressive, making it suitable for community aquaria, though it should be housed with other similarly adapted species.
