So it's been about a month since he went in the tank. My plans for him to stay on the ground did not last, he moved about a week after I put him in and has not moved since then. Apparently my talk with him about staying in one place did not work
He now pretty much covers the right side of the tank (i'll take some new shots tonight and post tomorrow). I had to move a couple corals around but everything came out fine. It really seems to be doing well in the tank, and already seems bigger.
In terms of a new tank, that was something we were already starting to price out. We are just debating on the size and type we want, but we know for sure it will be at least 200 gallons. We are hoping to have this setup before Christmas.
