Thanks for the insight. I was actually refering to a dottyback
. I do think they will work but:
1) I read that once a damsel "owns" a tank it will harass any new livestock
2) I don't have that much hiding space in my setup, I'll see if I can attach a picture
3) I have a 20 gallon tank.
I am leaning towards just adding some coral later down the road as I can see a dottyback and damsel fighting often.
As for a clownfish, aren't they damsels too? Interesting how they don't fight. Your friend must have a fairly large tank.
