The anemone arrived healthy and expanded well within a few weeks. It’s vibrant purple with long tentacles and looks great in my 40-gallon tank. I’ve added it to a reef setup with corals, and it hasn’t caused any issues so far. Good for intermediate aquarists who want a bold, colorful addition.

It’s a beautiful anemone with a strong presence. I noticed it gently touches nearby corals occasionally, but nothing harmful. The lighting and flow in my tank match the requirements, and it’s thriving. A bit of patience is needed during the acclimation phase.

I bought this for my beginner reef tank, and it’s been a success. The size is appropriate for a small setup, and it’s grown steadily. The color stands out well under moderate lighting. I’m happy with the purchase and would recommend it to others with similar setups.
