Bruce, don't you already have this fish in your 5 gallon reef at work?
I have never owned Talbot damsel's but damsels are reef safe, IMO. The problem lies in that damsels, for the most part, get very big, aggressive, and territorial. I didn't like to sell damsels as starter fish because people would come back and complain that the "big, mean damsel" is beating up on everything.
