The anemone arrived healthy and has been thriving in my 40-gallon tank. It’s colorful and adds a lot of visual interest. I’ve noticed it gently interacts with small fish but doesn’t harm them. Light and flow are set to moderate, which matches the care guide perfectly.

It’s a beautiful addition to my reef setup. The purple tentacles stand out well. I’ve kept it in a low area with moderate lighting, and it’s grown steadily over the past few months. A bit semi-aggressive, but not a problem with my tankmates.

Great quality and exactly as described. The size is within the M range, and it’s active and colorful. I appreciate the clear care instructions. It’s been stable in my 30-gallon tank with moderate flow and light.
