well I had a scare with this colony for some reason they closed for 2 weeks I thought they were going to die, THEY ARE OPENING TODAY! I have never had zoas close for that long and live, not in all my years of doing marine tanks. I was 98% sure they were going to die. I had another small cluster (I think it had 3polyps) but I shipped them to Murph145. so if I lost these I was out of luck on them. I am hoping murphs small cluster is open and doing great.
