The red-tailed black shark is a well-raised species with very low water quality requirements and prefers old water. Novices only need to be careful not to change new water during the breeding process, and the water temperature can be adjusted between 22°C and 26°C. The fish tank must be wide and slightly high, and planted with broad-leaved aquatic plants.

It should also be noted that juveniles can be kept in the same tank, but it is best to put only one fish in a tank when they grow up, because the red-tailed black shark has a unique concept of territory, and they often fight for the territory. .
