Long Tentacle Anemone: The Sand Dweller
The Long Tentacle Anemone (Macrodactyla doreensis) is one of the more common and hardier large anemones available in the marine aquarium hobby. Also known as the Corkscrew Anemone, Sand Anemone, or Red Base Anemone, it is easily recognized by its long, slender, often wavy tentacles and its column which is frequently a vibrant red or orange (the ‘Red Base’ moniker). Its oral disc often displays noticeable striping.
Native to the shallow, sandy lagoons of the Indo-Pacific, this anemone is a sand-dweller that buries its ‘foot’ deep into the substrate, leaving only the tentacles and oral disc exposed. It can grow to a considerable size, reaching a diameter of up to 10 cm.

This anemone arrived healthy and settled quickly in my tank. It burrowed into the sand right away and has been active ever since. The tentacles are long and colorful, adding a lot of visual interest to the display.

It’s a bit shy at first, but after a week it started extending its tentacles and interacting with nearby fish. The red base and striped oral disc are very striking.

I was worried about compatibility, but it’s peaceful and doesn’t sting any of my fish. It’s become a centerpiece in my reef tank.
