Yvonne Underwood –
The anemone arrived healthy and has been thriving in my 30-gallon tank. It’s colorful and adds a lot of visual interest. I keep it in the lower area where the flow is moderate and it’s not touching any corals. Very satisfied with the purchase.
Jessica McLean –
It’s a beautiful addition to my reef setup. The tentacles are long and vibrant. I’ve had it for about two months and it’s still active and expanding. Just make sure the lighting is moderate and avoid strong currents.

Great choice for intermediate reef keepers. It’s not aggressive but does require some space and stable water parameters. I placed it on a rock shelf and it’s settled well. Very happy with the result.
