This Sebae anemone is striking in color and adds a unique touch to my reef. I’ve had it for six months and it’s remained healthy despite the aggressive behavior. I keep it in a 55-gallon tank with strong lighting and medium flow. It’s a bold choice, but worth it for the visual impact.

The purple color is vivid and stands out in the tank. I expected it to be more aggressive, and it is—so I’ve had to carefully place it away from corals. It’s not for everyone, but it’s a beautiful addition to a mature reef setup.

It arrived healthy and looks great. I’ve noticed it extends tentacles when exposed to light. I’m cautious about its interactions with other invertebrates, and I’ve been monitoring closely. It’s a good visual centerpiece, but requires a stable and experienced setup.
