Well I picked another one up today. I watched them for a while, and picked one that was eating, and swimming around. His belly is white, and he has bright green on the top of him. He was one of the smallest in the tank, but he looked the healthiest.
I am acclimating him right now. But one thing that has me a little worried is that when I got him home I checked the pH, and salinity of the water he was in, and the pH was 9.0. Isn't that high? My reef tank is only 8.1-8.2. I put him in a little tank in my sump (separate from my tank water, but will keep the water temperature the same), and added a small amount of tank water to his original water from his bag. I raised the salinity up from 0 ppt to 3 ppt, and the pH came down to 8.4 (that is a fast drop in pH). He seems fine though. I feed some food, and he ate a little. I will add some more tank water in the morning, and keep doing that to slowly raise the salinity up over a week or so.
