The purple tentacles are striking and add a lot of visual interest to my 30-gallon tank. It has grown steadily over the past few months and remains healthy with moderate lighting. I keep it in the low area where water flow is gentle. It’s not overly aggressive, but I do watch for fish that might get too close.

Beautiful anemone with long, vibrant purple tentacles. It’s been in my tank for six months and is still expanding. I provide moderate water flow and light, and it’s doing well. A bit of caution is needed with small fish that swim too close.

Great addition to my reef tank. The color is vivid and the anemone holds its shape well. It’s not aggressive, and it’s adapted well to the moderate lighting and flow. I appreciate the clear care instructions included with the product.
