I rekon you should ditch the damsels
I rather like the 4-striped ones, but if you ant other fish they'll be a problem.
I rekon you should get a pair of clowns, nice little fish.
Maybe a gramma and some other little fish.
Possiblely about 3 fire gobies, i heard these are easy to keep
get some snails and shrimps. I dont like hermit crabs. get some peppiment or coral banded shrimps(these are beautiful
hope this has helped,
