In the aquarium a daily portion of sinking pellet, regular blanched vegetables and occasional frozen bloodworm or shrimp meet nutritional needs and reduce intraspecific aggression.
Compatibility

Breeding
Reproduces in fresh water without a planktonic larval stage. After mating, the female carries the eggs glued to her pleopods for several weeks; hatched juveniles cling to the mother for additional moults before becoming independent. Stable water chemistry and abundant shelter for the brooding female are required.
