I’ve had this anemone for three months in a 55-gallon tank. It’s vibrant and grows steadily. I keep it in a low area with strong lighting. It’s aggressive, so I have to monitor its behavior closely. Works well in a reef setup with proper care.

The anemone arrived healthy and has expanded to 5 inches. I maintain high light and medium flow. It’s not shy about moving around, so I place it in a corner away from corals. Needs expert attention, but it’s a striking addition to the tank.

It’s a large anemone and requires a lot of space. I noticed it touched a nearby coral after a week. I’ve since moved it farther back. Still, it’s visually impressive and shows good color retention under high light.
