Care
Care notes
This coral requires a mature reef tank with intense lighting (Metal Halide or powerful LEDs) and strong turbulent flow. Parameters must be stable: temperature 24-28°C, pH 8.1-8.4, salinity 1.023-1.025, calcium >400 mg/L, magnesium >1300 mg/L, KH 8-12 dKH. It is sensitive to nitrate and phosphate fluctuations (NO3 <10 ppm, PO4 <0.05 ppm). Beware of stinging tentacles at night: space it from other corals. Propagation by fragging is easy.
