Advice on next fish in my 55g (To be upgraded to 180g)

[Xyres]

So at the moment for fish/invertebrates I have:

Two clowns
Red stripe angel
Orange spotted diamond goby
Two emerald crabs
Turbo/cerith/nassa snails
Ten~ hermit crabs

For corals I have

Frogspawn
Hammer coral

So as you can see as far as corals go I am not doing anything too fancy until I get my larger tank in about a year. I was looking for something that will get along with blue throat triggers and tangs in my next tank. Any advice would be great, even if the advice is not to get another fish. I wouldn't want to overstock my tank.

Thanks everyone!
