I'd give up a few chromis for a pair of clowns and some gobies or blennies. You're gonna want something that hangs out on the sand bed and maybe perches on rocks. All those you mentioned are gonna be swimming out front. Variety is gonna be more pleasing to you IMO
I'm doing a naso, purple, and bristletooth in my 155g. All from different lines of tangs so no one's similar body shape causes friction.
I'd think you should stop at the three if that much. Go for 3 or 4 chromis IMO
. Anthias need feeding more often, so do some research on those too before you decide. Ideally, I like to be where I don't have to feed but every other day for the most part.
