About

Feeding
Omnivore. Accepts marine flakes, pellets, brine shrimp, mysis and frozen foods. Eats practically any food offered, very easy to feed.
Breeding
Oviparous. Male builds a nest on a clean surface and actively courts females. Aggressively guards the eggs. Breeding possible in an aquarium.
Care Notes
Aquarium with plenty of hiding spots to establish territories. Introduce it last in the tank. One specimen per small aquarium. It can be kept with assertive fish that aren’t intimidated.
