What fish or shrimp should I add to a tank with a damsel already in it?

[Datreeferman]

Thinking of adding shrimp and fish to my saltwater aquarium. Can I add a shrimp to my aquarium that has a damsel in it? Will it be ok? Can I add a fish to my aquarium with a damsel in it? Will the fish be ok? Is their any techniques to introduce shrimp or fish to an aquarium with a yellow tailed damsel safely? And since this will be my last fish added to the aquarium what should I get? I want it to be unique and reef safe. Also in the price range of 5-30$. What type of shrimp should I get?what type of shrimp would be most helpful to my aquarium? Also in the same price range.
If you want to know what I have in my aquarium so the shrimp/fish that you recommend me can be Compatable to what I have, I got:
A pair of clown fish
A fire fish
1 yellow tailed damsel
Hermit crabs
Snails
Feather duster worm
and Corals.

If this is your 25 gallon, I wouldn't be adding anything else, fish-wise...... You're pretty well stocked as it is. And, Damsels are typically problematic towards other fish, not inverts..... you could probably put a cleaner shrimp in there if you'd like, but I'd probably call that it as far as that tank goes.
