Family Zoanthidae

Isaurus tuberculatus

Gray, 1828

Snake Polyps, Warty Sea Mat

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: South Africa to Hawaii, and south to Australia.

Natural Environment: Inhabits intertidal rocks.

General Husbandry: Occasionally seen in the trade.

Polyps are generally closed during the day in the wild, and open at night to feed on plankton. See photo with open polyp feeding.

Nevertheless, it does contain zooxanthellae, and supplemental feedings of baby brine shrimp will help the polyps multiply.
