Care notes
A tank of at least 100 liters is recommended, with moderate to intense lighting and low to moderate flow. Stable parameters are essential: temperature 24-27°C, pH 8.1-8.4, salinity 1.023-1.025, calcium >400 ppm, magnesium >1200 ppm, KH 8-12 dKH. It tolerates nitrates up to 20 ppm and phosphates up to 0.1 ppm. It feeds on zooplankton and can be target-fed meaty foods. Beware of stinging tentacles at night; space it at least 15 cm from other corals.
