Care, breeding and tankmates
Aquarium Setup: Must have a soft sand bed at least 5 cm deep. Decorate with stable rockwork. Avoid sharp gravel.
Diet and Feeding: Active carnivore. Known to consume flatworms, pyramidellid snails, and other reef pests. Feed mysis, artemia, and pellets.
Water Quality: Reef-safe parameters are required. Standard mechanical and chemical filtration with an active protein skimmer.
Compatibility and Cohabitation: Safe with corals. May eat tiny ornamental shrimps or fan worms. Peaceful with other fish.
Aquarium Breeding: Protogynous hermaphrodite. Spawning has not been achieved in private home aquariums.
Risks and Diseases: Jump risk when first introduced. Prone to skin injuries if kept with coarse or sharp substrates.
