Palythoa tuberculosa
A Palythoa that incorporates abundant sand into its coenenchyme, forming thick, massive sheets over rock. The polyps are sunk deep into the tissue with only the oral disc exposed. Handle with care: it carries palytoxin.
Palythoa tuberculosa is a zoantharian of the family Sphenopidae distributed widely across the Indo-Pacific. SeaLifeBase gives its depth range as 0-20 m, and it forms thick sheets over rock from the intertidal zone onto shallow reef slopes. It takes abundant sand into its coenenchyme, so colonies are hard, and the polyps are sunk deep into that tissue with only the oral disc exposed - the character that separates Palythoa from Zoanthus. Colour is generally brown or greyish green with plain oral discs. It is zooxanthellate and draws most of its nutrition from photosynthesis. This species is known to carry palytoxin, and poisonings have been reported from fragging it and from heat-treating rock bearing colonies. Do not work on it bare-handed, and never use boiling water or a pressure washer on colonised rock. Husbandry itself is easy and the animal is hardy, but it spreads vigorously and takes over rock, so in a reef tank it needs a position that limits its expansion. It is not listed in the CITES Appendices.

Mainly nutrition from symbiotic zooxanthellae, supplemented with liquid or powdered coral foods.
Stable under moderate lighting. It grows into the intertidal zone and tolerates bright light, but it is hardy enough to hold across a wide range of intensities.
Give moderate randomised flow and place it at mid-height on the rockwork. It sheets thickly over rock, so in a reef tank keep it on an isolated rock to limit its spread.
Water 24-27C, specific gravity 1.023-1.025 (33-35 ppt), KH 8-12. Colour and spread are steadier with a trace of nutrients present than in ultra-low-nutrient water.
Most of its nutrition comes from photosynthesis. Liquid or powdered coral foods may be offered as a supplement, but it can be maintained without feeding.
This species is known to carry palytoxin, and poisonings have been reported from fragging it and from heat-treating colonised rock. Do not frag it bare-handed and never use boiling water or a pressure washer; wear gloves and eye protection. It is not listed in the CITES Appendices.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Palythoa Tuberculosa is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Palythoa Tuberculosa typically reaches Polyps 1-2cm across as an adult. Size may vary depending on care conditions and individual genetics.
Palythoa Tuberculosa feeds on: Mainly nutrition from symbiotic zooxanthellae, supplemented with liquid or powdered coral foods.. Aim for a balanced diet with appropriate feeding frequency.
