Fish with a lotta personality?

[Grey Reefer]

I have 20g Nano reef that I'm going to go in the SPS direction. So there will be alot of light in the tank and high flow. I'm looking for a fish and/or fishes. With cool personalities for the tank. Right now I have a Cerulean Damsel (Chrysiptera Hemicyanea) in the tank. I've had the Damsel for 3 years now and has been the sole resident (at least fish) in one of my smaller nano reef's (I consolidated) . From what I've read about this little guy , he is not as aggressive as most damsel fish, but I've never kept him/her before with other fish.

I'd vote for the watchman, holds its own, doesn't pick, and is friendly and up front, plus lots of little subtle green dots, real attractive.

Firefish! Inexpensive; produces little waste; will be out in the front of the tank for you to enjoy.
