I have had yellow tail blue damsels (C. parasema) and several other types of damsels. I would recommend the yellow tail blue as the best and least aggressive of any damsel I have had experience with. I keep one in my 55 gallon tank and it gets along well with my clownfish, mandarin fish, and yellow watchman goby. It gets fiesty once in awhile but the group get along fine. I got rid of my other damsels (the ones that survived all of the aggression). I also had three in a 75 gallon tank that included other types of fish. If you decide on multiples put them in all at the same time.
