live stock addition suggestions

[prisoner1572]

Here is my current stock in my 125g tank:
blue tang
ocellaris clown
green pseudochromis
6 line wrasse
scooter blenny
nassarius snail
hermit crab

Is there anything else that I can get that would be compatible with my current livestock? It seems like the wrasse would be the limiting factor. Are inverts like shrimp out of the question? What about getting into corals, polyps and anemones? I was thinking about bangaii cardinals on the fish side of things.

Cardinals will work just fine and you can get shrimp with your current stock as well ...Your 6 line won't bother them
