Last thing, I was going to try moving the Duncan coral today to a different spot. Although the skin has remained healthy and the feeders are out often, it has yet to fully open. Then today, it actually opened up just a little bit. I decided to give it a little more time in this spot and will revisit next weekend.
Duncans can sulk for weeks after transportation or even being moved in the tank ime, leaving it until next week sounds good to me.
