Sophie Walker –
Bought this for a 50-gallon reef tank. It grew well under high light and medium flow. The color is a mix of green and purple, as described. Very active and needs space. Watch out for it chasing smaller corals. Overall, a striking addition to the tank.
Steven Clark –
Installed it in a well-established tank. It settled in the low area and expanded over several months. Requires careful placement to avoid damaging nearby polyps. Not for beginners, but worth it for experienced aquarists.
James Fisher –
The anemone has been thriving for over six months. It’s large and vibrant, with a strong presence. I keep it away from shrimp and small fish. The lighting and flow are critical—follow the guidelines exactly.
