Zoanthus sansibaricus
The polyps of Zoanthus sansibaricus are small, with a crown of tentacles around a central mouth. Color varies from green to brown, sometimes with orange or pink hues. They form dense mats on rocks. They contain symbiotic zooxanthellae. They can retract quickly when threatened. They reproduce by budding. They are hardy but can be sensitive to parameter fluctuations.

Care
Care notes
Temperature 24-28°C, pH 8.1-8.4, salinity 1.023-1.025. Moderate to strong lighting. Moderate flow is beneficial. Calcium 400-450 ppm, magnesium 1250-1350 ppm. Nitrates <10 ppm, phosphates <0.05 ppm. They tolerate a wide range of conditions but stable water is preferred. Feed with phytoplankton or liquid coral foods. Watch for filamentous algae that can smother them.
