Flowerpot Coral

Environment

Mature reef aquarium minimum 200 liters, imperative chemical stability (calcium 400-450 mg/L, KH 8-12 dKH, magnesium 1250-1350 mg/L). Moderate to medium lighting (PAR 75-150), placed in mid or lower zone depending on species. Medium, alternating flow, not direct. Sandy substrate or placement on stable rock. Avoid sudden parameter changes.

Feeding

Feeds mainly through photosynthesis (symbiotic zooxanthellae) but must be supplemented 2-3 times/week with phytoplankton, zooplankton, liquid coral foods or artemia nauplii. Target feeding recommended in the evening when polyps are extended.

Health & common diseases

Goniopora are sensitive to stress and bacterial infections (tissue necrosis, browning or bleaching of polyps). Poor water quality, inadequate lighting or unstable parameters can cause prolonged polyp retraction and progressive deterioration. Prevention relies on very stable water (calcium 400-450 mg/L, KH 7-9, magnesium 1250-1350 mg/L), moderate flow, adapted lighting and regular phyto/zooplankton feeding. Avoid frequent handling and monitor any sign of retraction or discoloration.

Tips & tankmates

Demanding coral, not recommended for beginners. Very sensitive to stress, delicate transport and acclimation. Monitor prolonged polyp retraction (sign of stress/disease). Can slowly deteriorate without apparent cause. Space away from other corals (low aggression but harmful contact). Regularly test nitrates (<10 mg/L) and phosphates (0.03-0.1 mg/L). Patience essential: long adaptation period.
