The anemone arrived healthy and looks beautiful in my 30-gallon tank. It’s active and shows interest in leftover food, which is entertaining to watch. I’ve had to be careful with other fish, but it’s not aggressive toward them directly. It’s a unique addition to the tank.

It’s a striking purple color and stands out in the sand. I noticed it grabbing food pieces, which is a fun behavior. I keep it in a low-light setup and it seems to be adjusting well. A bit of caution needed with smaller fish.

Beautiful and unique. The color is deep and consistent. It’s not overly aggressive, but it does extend tentacles and react to movement. I appreciate the natural behavior it shows. Works well in my low-flow tank.
