OCL/PSK mix with yellow tail damsel?

[Stence]

I read in "marine fishes, 500 common species", that the Yellow tail damsel is the least aggressive of the damsels (beside from clowns) and was wondering if I could add him to my 50 gallon with my false percs and pink skunks? Are they too closely related all being damselfish.

PS. can anyone define conspecific? as in "This fish (S.picturatus) will attack male conspecifics"
I am thinking it means the same species...?

Conspecific- An organism belonging to the same family as another.

I wouldnt add damsels with anything but damsels, they can become a PITA down the road.
