Skunk loach

The skunk loach, skunk botia or Hora's loach (Yasuhikotakia morleti; syn. Botia morleti, Botia horae, Botia modesta) is a species of botiid loach found in the Mekong River basin in Indochina, as well as the Chao Phraya and Mae Klong basins in Thailand.[1] The maximum size is 10 cm (4 in) and it occurs in water with parameters 26 - 30 ° C (79 to 86 ° F) temperature, pH 6.0 to 8.0, hardness 5.0 to 12.0. It feeds on live crustaceans, insects, snails and other invertebrates.

In the aquarium[edit]

Despite being seen frequently in the aquarium trade, it is a very aggressive fish and not suitable for community aquarium tanks. Other smaller fish and bottom feeders in the tank may be attacked or killed. Suitable tank mates for the skunk botia include larger cichlid species. Caves should be provided as hiding places.
