Suggestion for Tank Mates

[ScubaGirl]

Hello!

I got a gift certificate to the LFS for Christmas and want to get one or two new fish with it. I'm looking for suggestions. The LFS has a chalk basslet, a coral beauty and a flame angel in stock. Maybe the chalk with one of the angels? I've been doing research and checking compatibility and none of these are ideal for what I have from what I have read. Any of you had luck with these combos?


I currently have these fish:
1 Yellow tang
2 Clowns
1 Blue damsel
1 Canary Wrasse

Inverts:
Cleaner shrimp
Coral banded shrimp
Conch
Snails
Blue Hermit crabs (maybe 1-2 left)
Pom Pom Crab
Tuxedo urchin
and a sand sifting star fish

* I have my heart set on trying another clam one day now that I have the wrasse.

Corals:
Hammer
Xenia
Anthelia
Open Brain
Trumpet
A very cool single brown/white polyp that I don't remember the name of (Chaloupa help! LOL)

It's a 75 gallon tank with tons of live rock/caves/hiding. We don't have a huge amount of algae either. It's a happy little world in there right now so I don't want to get something that is going to bully or pick at the corals.

Any suggestion is greatly appreciated! I want to spend my Christmas $$$.
