Botia is a genus of freshwater fish in the Loach family (Cobitidae). It was a large genus with about 20 species. In 2004 Maurice Kottelat proposed in his paper (along with the description of Botia kubotai, see References below) to divide the genus into four related genera based on the fish appearance and locality:

Botia for Indian loaches (shorter body).
Chromobotia for Clown loach.
Parabotias are quite like the tiger loaches, mostly chinese.
Syncrossus for tiger loaches (elongated body).
Yasuhikotakia for Mekong loaches (shorter body).

The fish in these genera possesses a pair of spines under the eye sockets. They are normally hidden but may be extracted when the loach feels threathened. This behavior is infrequently observed. However, care has to be taken when catching it using fishnet as the extracted spines may get entangled to the nets causing injury. One special capability of these loach group is the ability to produce loud “clicking” noise. It is commonly heard during feeding time. Many loach individuals prefer to sleep on their side or other strange positions.

The most well known fish of the group is the Clown Loach (Chromobotia macracanthus), which is often kept by aquarists.
