Stocking suggestions?

hi people, first off I have a 24x24x24 cube, beleive that's around a 55gallon, not sure I'm used to litres lol anyway I've got a sump setup with filtration and skimmer, etc. I have what I beleive to be alot of love rock, 40kgs or so.
Current stock
2 percula clowns
1 red coris wrasse(yes prob outgrow eventually, couldn't resist him)
1 torch coral
1 patch of green star polyps
1 elegance coral
Duncan, candy cane and zoa frags
1 tree like coral (haven't researched yet)

Now my local fish store is bare at the moment due to bad weather and delays but in a week or so they will be overstocked with everything and cutting prices, I am after suggestions to go with what I have, all I have in mind for now is a Flame angel. What others would people suggest? And are all inverts out of the question due to my wrasse? Would still like a clean up crew of some sort?

 

Yeah I think that tank is 55-60 gallons although with all that rock in there your actual water volume in the tank is more like 50-55 gallons.

How about a McCosker's flasher wrasse male with 2 females? Watching them flash for the females is really cool. I'm planning on them for my new tank.

Inverts sound like they're out.
"In nature the coris will eat shelled mollusks including hermit crabs, urchins, tunicates. Snails will be picked on."
FAQs on Wrasse Compatibility

Aside from size they also can get aggressive as they get older so you really might want to start planning a solution for that.

Everyone has a flame angel. yes they are pretty, but so unoriginal. If you are shooting for a dwarf angel, go with something a little less common, like a potters or a flameback.
