Size: Column length 16 inches (40 cm), 1.5 inches (3 cm) wide.
Natural Environment: Found worldwide in tropical and sup-tropical seas, primarily in sandy or muddy bottoms, living singly at various depths along coastal waters
General Husbandry: Generally seen in the trade as small specimens, e.g., disc area about 1 inch (2.5 cm) across, with tube length about 4 inches (10 cm), with long purple tentacles, and a green mouth area.
Quite attractive, yet needs to be fed nightly finely minced krill, fish, shrimp or mysis shrimp.
Grows fast when fed nightly, and therefore needs a deep sandbed, e.g., at least 6 inches (15 cm) to remain healthy. They also have a very strong sting that can harm tankmates, and will eat fishes and crustaceans. Not safe as a clownfish host!
Most specimens seen in the trade come the Philippines. Best kept in environments that suit its needs!
