Species description

Geographical Origin and Habitat: Distributed in the Southwestern Pacific Ocean, notably around the Great Barrier Reef of Australia, New Caledonia, and the Loyalty Islands. Found in reefs at depths of 1 to 25 meters.

Taxonomy and Morphology: Member of the family Pomacentridae. Oval and compressed body shape. Reaches a maximum standard length of 10.3 cm. Possesses rounded fins characteristic of anemonefishes.

Social Behavior: Forms mutualistic relationships with host anemones. Shows territorial behavior dedicated to protecting its host anemone, although it is generally less aggressive than larger clownfish.

Coloration and Sexual Dimorphism: Orange-brown base color with two black-edged vertical white bars. The tail and tail base are white. Females are larger than males, displaying sexual dimorphism.

Care, breeding and tankmates

Aquarium Setup: Requires a minimum tank volume of 120 liters with structured rockwork. Host anemones like the Bubble-Tip Anemone (Entacmaea quadricolor) are highly beneficial for husbandry.

Diet and Feeding: Omnivorous diet. Feeds on zooplankton, frozen foods (artemia, mysis), and high-quality prepared foods including marine algae flakes or pellets.

Water Quality: Requires marine water parameters: temperature 24-28 °C, pH 8.1-8.4, and salinity range of 1.020-1.025 with proper water movement.

Compatibility and Cohabitation: Compatible with reef-safe tankmates. Avoid introducing multiple pairs of clownfish to prevent territorial fights. Keep with peaceful reef fishes.

Aquarium Breeding: Oviparous and protandrous. Deposits demersal eggs on flat rocky surfaces near the host anemone. The male maintains and guards the nest until hatching.

Risks and Diseases: Prone to typical marine parasites such as Marine Ich and Brooklynella. Quarantine is recommended for wild-caught specimens to ensure acclimation success.

Reproduction
Ermafrodita proterandrico. Depone uova demersali su superfici lisce vicino all'anemone ospite, sorvegliate attivamente dal maschio.
Compatibility & tankmates
Moderatamente aggressivo. Difende l'anemone ospite con vigore, ma è compatibile con pesci di barriera pacifici.
