The red-tailed black shark can be reproduced, but artificial reproduction is more difficult. The requirement is to stabilize the water temperature at 26°C, and the water quality is weakly acidic. The length of the aquarium used should be 60 cm, and the bottom of the aquarium should have Sand for bedding.

Red-tailed black sharks can only reproduce with one male and one female. When the eggs hatch into fry, the body color is black and the tail is yellow.
