Adrian Nash –
Received the Green Sebae Anemone in good condition. It has expanded nicely in my 55-gallon tank with high lighting. I’ve had to monitor it closely due to its aggressive behavior, but it’s now a striking addition to the reef. Strong recommendation for experienced aquarists only.
Adam Fraser –
The anemone arrived healthy and has settled well in my tank. I keep it in a corner with no other anemones to avoid conflict. It’s vibrant and active under high light. Requires constant attention, but worth the effort for a rare and beautiful species.
Olivia Hunter –
It’s a beautiful specimen, but I had to remove a small coral neighbor due to its aggressive tentacle movements. I’m cautious now and only place it in a secure area. Not for small tanks or new hobbyists.
