I’ve had this anemone for three months in a 75-gallon tank. It’s quite active and has expanded to 9 inches. I keep a close eye on it because it can be aggressive toward other invertebrates. The lighting and flow are set to high and medium as recommended. It’s a striking addition to the tank, though it demands expert care.

The anemone arrived healthy and has grown steadily. I maintain high light and medium flow. It’s not shy about moving around and sometimes touches nearby corals, so I’ve had to adjust placement. Still, it’s visually impressive and adds a lot of color to the tank.

It’s a large anemone and takes time to settle. I noticed it was aggressive toward a small shrimp. I moved it to the lower part of the tank and now it’s stable. I’m cautious about adding new species near it.
