Family Corallimorphidae

Pseudocorynactis caribbeorum

Den Hartog, 1980

Orange Ball Anemone

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Western Atlantic Ocean: Caribbean.

Natural Environment: Inhabits reefs and sandy areas near reefs, and seen down to about 100 feet (30 m). Nocturnal, solitary polyps extend from recesses or sand. If disturbed or lighted, this corallimorph will retract.

General Husbandry: Not purposely collected for the trade, yet may show up occasionally.

Has a bright orange body column and ball-like tips on nearly transparent tentacles. Disc is up to 2 inches (5 cm) in diameter. Occasionally, the column and tentacles may be pale yellow or white.

Would require hand feeding of meaty foods at least twice a week.


    Kingdom: Animalia

    Phylum: Cnidaria

    Class: Anthozoa

    Subclass: Hexacorallia

    Order: Corallimorpharia

    Family: Corallimorphidae

    Genus: Pseudocorynactis/Corynactis

FYI: When sensing meaty foods entering the aquarium, the species will open up and accept foods, however, if done so in a lighted condition, will retract after being fed.

More a unique species than the average aquarium species.

Extremely sticky, and best suited for a species-specific environment.

Will sting corals, eat small fishes, snails, shrimp and crabs that touch it.
