This anemone adds a striking green color to the tank. It thrives under high light and medium flow. I’ve had to keep it isolated from other species due to its aggression. It’s a beautiful addition to a well-established reef setup.

Installed in a 50-gallon tank with proper lighting and flow. It expanded slowly and stayed healthy. The color is vibrant, though it does sting nearby fish. Requires constant monitoring.

It’s not for beginners. I expected more growth, but it stayed small. Still, the visual impact is impressive. I keep it in a low area with no other anemones nearby.
