Looking good m0nkie.
Can't wait to see him in DT.
If you don't have any anemone in DT, you don't have to wait to transfer. If you do, then 3+ days with no deflation is enough IMO.
Initially, I don't put anemone in their permanent place but I put them on a rock or cup or whatever they attached to (in hospital tank) in an open area. If they do well there, I transfer them to permanent place. I am usually pretty good in picking place for my Magnifica, Gigantea and Haddoni. All most all the time they stay where I put them.
I really hate to separate anemones from their attachment. IMO, this really stress them. They often do it themselves if we put them in a less than ideal situation.
