The Radium Green anemone is vibrant and very active. It grabs food regularly and adds a lot of interest to the tank. I’ve had it for three months and it’s thriving in my 40-gallon tank with medium flow and low light.

It’s a striking color and quite lively. I noticed it interacting with other tank inhabitants, though it does show some aggression toward smaller shrimp. Works well in a sand bed with proper lighting.

Great addition to my reef setup. The color stands out, and it’s very active. I appreciate how it helps keep the tank dynamic. Only issue is it needs a bit of space to avoid stressing nearby corals.
