Common name: Branching anemone

General information

The Hell's Fire Anemone, Actinodendron plumosum, is a striking species known for its long, venomous tentacles that resemble the branches of a soft tree. This invertebrate is not a true anemone but belongs to the order Actiniaria. It is often mistaken for a coral due to its appearance. The tentacles contain potent stinging cells called nematocysts, which it uses to capture prey and defend itself against predators.

Care

Hell's Fire Anemones require an experienced aquarist due to their aggressive nature and potent sting, which can harm other tank inhabitants. They need a well-established aquarium with stable water conditions, moderate to strong lighting, and moderate water flow. It's crucial to provide ample space between them and other tank inhabitants to prevent accidental stings.

Reproduction

In the wild, Actinodendron plumosum can reproduce both sexually and asexually. In the aquarium, they may occasionally divide, leading to asexual reproduction. Sexual reproduction in captivity is rare and not well documented.

Symbiosis

While not known for hosting fish, Hell's Fire Anemones can have a mutualistic relationship with certain types of clownfish in the wild, which may seek refuge among its tentacles. However, due to their potent sting, this is less common than with other anemone species.

Habitat

Actinodendron plumosum is typically found in the Indo-Pacific region, from the Red Sea to Australia. They inhabit sandy bottoms and reef slopes, often burying their base in the substrate to anchor themselves securely.
