Green zoanthid
Zoanthus sociatus
CoralMarine
Polyps reach up to 2 cm in diameter and are bright green to olive green, sometimes with brown or yellow hues. They form dense mats connected by a common coenenchyme. Tentacles are short and arranged in two circles. This species is photosynthetic via its zooxanthellae and extends polyps during the day. No obvious sexual dimorphism.

Care notes
Minimum tank size: 40 liters. Parameters: temperature 24-28°C, pH 8.1-8.4, salinity 1.023-1.025, nitrates < 20 mg/L, phosphates < 0.1 mg/L. Lighting moderate to intense, flow moderate. Feeds mainly through photosynthesis but may accept plankton. Beware of stinging tentacles that can damage neighboring corals. Easy to propagate by fragmentation.
