Care notes
Maintain a temperature of 24-28°C, pH 8.1-8.4, and salinity 1.020-1.025. A minimum tank volume of 100 liters is recommended for a single specimen. The aquarium should have plenty of hiding places (live rock) and open swimming space. It is omnivorous: feed with flakes, pellets, brine shrimp and mysis. It can be kept in a group in a large tank, but cohabitation with other damselfish may be conflictual. Avoid overly timid fish as it may harass them. Efficient filtration and regular water changes are necessary. It is sensitive to nitrate and phosphate spikes.
