The problem is Damsels get big, territorial and aggressive. In a 20 gallon tank it is very possible that they will kill any other suitable tank mate.
Seriously. Damsels get flat out mean. Pet stores sell them because they are cheap. 30 years ago when this hobby was poorly understood they were used as "test" subjects in aquariums.
Our hobby has progressed a long way since then. We now more fully understand the Nitrogen cycle in marine aquariums. These sacrificial lambs are no longer a neccessity. The fact that pet stores still push them for new tanks should tell you they aren't keeping up with the newest info in the hobby.
You did what many of us did when we first set up our tanks. You listened to the people who you trusted selling you the fish. now, as hobbyists here, looking to gain not a cent from you, we're telling you they were taking advantage of ya.
Any fish, whether $5 or $500, becomes your responsibility the moment you buy it. It is your responsibility to give it the proper habitat.
Not lecturing you, just trying to help! This can be an amazing and rewarding hobby, or it can be a time/money pit.
