zoanthid
Soft coral relative
A zoanthid is a small colonial marine animal related to corals and sea anemones, typically found in shallow tropical waters.
Zoanthids form mats of polyps on rocks, coral rubble, or other surfaces, often displaying vibrant colors that make them popular in home aquariums.
Some species harbor potent toxins.
The reef tank was covered in zoanthids.
