Natalie Burgess –
The purple tentacle anemone grew well in my 30-gallon tank with moderate lighting. It’s active and colorful, though I had to keep it away from a few sensitive corals. It’s a striking addition to the display.
Carol Knox –
Grew steadily over three months. The color is vibrant and the tentacles extend nicely. I placed it on the lower shelf and it’s not causing any issues with other invertebrates.
Faith Dyer –
Great for intermediate reef keepers. It’s more active than expected but not aggressive. I’ve maintained stable water parameters and it’s thriving.
