want to add fish to tank. recommendations please

[Knox_Legend]

Ok, so in my current 135 gallon tank I have a Sailfin tang,coral beauty,sixline,yellow tail damsel and some blennie who lives in a rock and various cuc. Right now it is a fowlr with a few mushrooms. I am keeping it fowlr until I can get it set up for a true reef setup and was looking for additional fish selections and suggestions from fellow reefers out there.

I would like a clown pair eventually and for some reason I can't stop thinking about a niger trigger( I know not reef safe). Like I said I'm just open to suggestions and wondering what would go good with the current inhabitants.

Thanks all
