Keith Bond –
I’ve kept this anemone for six months in a 50-gallon tank with strong lighting and medium water flow. It’s active and colorful, though it does sting other small invertebrates. Requires careful placement and monitoring. Worth it for experienced reef keepers.
Paul Poole –
The tiny specimens arrived healthy and stayed stable in my tank. I keep them in a low area with high light. They expand slowly, and I’ve noticed they are quite territorial. Not for new hobbyists.
Robert Lee –
It’s a striking addition to the tank, but I had to remove a small shrimp that got damaged. The anemone is aggressive and needs a well-established tank with strong flow and high light.
Warren Springer –
After months of adjustment, the anemone has grown steadily and looks vibrant. I maintain high light and medium flow. It’s a beautiful species, but only for those who understand its behavior and care requirements.
