The purple tentacle anemone looks stunning in my 30-gallon tank. It has grown steadily since I added it three months ago. I keep it in a low area with moderate lighting and it’s not causing any issues with my corals. A bit of caution is needed with small fish, but overall it’s a beautiful addition.

It arrived healthy and has been thriving in my tank. The color is vibrant and the tentacles move naturally. I’ve noticed it’s slightly more active in the morning. I keep it away from darting fish to avoid any contact.

Great choice for intermediate reef keepers. It’s not aggressive, but it does extend its tentacles when touched. I place it on a rock shelf with moderate flow and it’s doing well. No signs of stress or fading.
