I’ve kept this anemone for six months in a 75-gallon tank with strong lighting and medium flow. It has grown steadily and remains active. I’m cautious about its aggression and keep it in a low-traffic area. It’s a striking addition to the reef, though not for beginners.

The anemone arrived healthy and has been thriving in my 50-gallon tank. I’ve had to remove a few small corals due to its aggressive behavior. It’s beautiful and bold, but requires constant monitoring.

I expected a more peaceful anemone. This one is very active and has chased away several small shrimp. I’m still learning how to manage its placement and lighting.
