Get a damsel if you WANT a damsel, not just because they are a hardy easy to keep fish... they can be aggressive, so know about the fish going in... (as with ANY fish you intend to purchase)
I have a mated pair (laying and tending to eggs) of blue and yellow damsels, and they are in the same 60 gallon tank as a pair of clowns. (That makes two pairs or damsels in a kind of small space) They each have their territory, and honestly are great fish to observe.
