In the wild, the Wetmorella nigropinnata will feed on small invertebrates. In aquariums, these fish are accustomed to eating replacement foods such as frozen shrimp meat and frozen plankton. They can also be accustomed to dry food in the form of pellets and flakes, as well as to artemia, small krill and mizid. It should be noted that the substitute feed fish adapt within a few weeks, after that any problems with their feeding does not arise. Feed the fish once or twice a day.


Although some reports suggest it is possible, they are not bred in the aquarium. All fish, in limited numbers, are supplied to the domestic market from their natural habitat.
