Briareum asbestinum

(Pallas, 1766)

Caribbean Corky Finger, Deadman Fingers

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Western Atlantic Ocean: Southern Florida, Caribbean, Bahamas, and Bonaire.

Natural Environment: Inhabits coral reefs and rocky bottoms from depths between 3 - 40 feet (1 - 12 m) where it forms low growing clumps/mats with columns and can reach heights of about 24 inches (60 cm).

General Husbandry: Occasionally seen in the trade and has an encrusting base with upright columnar growths covered with large wavy polyps.

Requires fairly good water movement and strong light. Occasional feedings with plankton-like foodstuffs is quite beneficial.
