Breeding
In the wild it migrates onto flooded plains to spawn during the monsoon. It is not bred in home aquariums, and trade fish are produced by hormone-induced spawning on farms.
Good to know
Sold small but grows to around 50 cm or more and becomes very territorial, so it needs a huge tank or a heated pond. Do not confuse with the much smaller red-tailed black shark (Epalzeorhynchos bicolor).
