Leather coral

Environment

Minimum 200-liter reef aquarium, mature and stable. Temperature 24-26°C, salinity 1.023-1.025, pH 8.1-8.4. Requires moderate to intense lighting (LED or T5) and moderate to strong water flow, with alternating current to prevent detritus accumulation. Place on stable rock, in middle zone with space for growth. Calcium 400-450 mg/L, KH 7-10 dKH, magnesium 1250-1350 mg/L. Avoid direct contact with other corals (toxins).

Feeding

Derives most of its energy from photosynthesis through zooxanthellae. Can capture microplankton and benefit from occasional feedings of phytoplankton, zooplankton or liquid coral foods (1-2 times/week). Feed in the evening when polyps are extended. An aquarium with developed microfauna is beneficial.

Health & common diseases

Leather coral is sensitive to bacterial infections manifested by persistent shrinkage, discoloration or necrotic areas on its surface. Tissue necrosis (RTN/STN) can occur due to stress from poor water quality or strong parameter fluctuations. To prevent these problems, maintain stable parameters (calcium 400-450 mg/L, KH 7-10, magnesium 1250-1350 mg/L), ensure moderate water flow, and monitor nitrate and phosphate levels. A temporary retraction phase after introduction or shedding of the mucus layer is normal and should not be a concern.

Tips & tankmates

Periodically, Lobophytum sheds by producing a waxy film: it retracts completely for 2-7 days, this is normal. Never remove this film manually. Beware of toxic secretions (terpenes) that can affect other corals: ensure filtration with activated carbon and regular water changes. Compatible with reef fish and peaceful invertebrates. Avoid predators (certain butterflyfish, crabs). Easy fragmentation for propagation. Monitor water quality, avoid nitrates >10 mg/L and phosphates >0.05 mg/L.
