Family Actinodendronidae

Actinodentron arboreum

(Quoy & Gaimard, 1833)

Tree Anemone, Hell’s Fire Anemone

Not Reef Tank Suitable

Not Suitable for Fish-Only Tank

Range: Eastern Indian Ocean and Western Pacific Ocean

Size: 12 inches (30 cm)

Natural Environment: Inhabits shallow reef waters in sheltered areas having sandy or rubble bottoms.

Aquarium Suitability: A singly living burrowing anemone that looks somewhat like soft coral. When threatened it retracts into the sand.

Unsuitable for home aquariums, yet if desired for a species specific environment, can be fed, twice a week, chopped silversides, shrimp, krill, mussels, and/or freshly chopped fish.


    Kingdom: Animalia

    Phylum: Cnidaria

    Class: Anthozoa

    Order: Actiniaria

    Family: Actinodendridae

    Genus: Actinodentron

FYI: Be aware they are poisonous and their sting is very painful! Wear gloves if handling this species! They will move about the aquarium and can easily damage and kill corals, besides stinging and eating fish that get too near its tentacles.

Not purposely collected for the trade, and since it has a potent toxin, better left in the wild.

Temperature range of 72 to 82°F (22 - 27°C).

Does not require light, as it's only a carnivorous species.
