Nano's 35g Cube

[Nano]

Hey Guy's its that time of year, where I get the itch to do something.
So I bought a use 35 gallon cube tank! I am hoping to do something truly
elegant, and different with the aquascape, but I need some suggestions.
its 24x24x15 so my height is a bit limited, but I am thinking 2 pillar
structures, one larger one in the back corner, and a smaller on middle
or front corner area. Both would have some shelves coming out of them.
Again open to suggestions

Equipment

Lighting
AI SOL super blue
AI controller
Still thinking of refugium light, most likely small t5/CFL supplemented with my old nano leds strips

Skimmer
Tunze 9002

Powerheads
2 Koralia 240

Custom Oak Stand built by yours truly (had some wild cherry I was going to trim it with, but decided against it), Custom AI mounting Arm being built By Greg(Thanks So much!!), not sure if I'll paint it white to match the SOL or black to match the eurobracing. (again open to suggestions)

Still figuring out the sump/fuge (will update)

The DT will be all Dry rock for aquascaping reasons, and all my live rock
will go in the sump, all though I might put one or 2 small chunks in the DT
temporarily.

I have 2 ocellaris, one bangai, one scooter blenny, that I plan on putting
in, and am looking at maybe 2 more fish, so suggest some! I want some
nice color but also functional fish (i.e. pest eaters)

Current CUC consists of
1 emerald crab
4 Hermits
2 Astrea snails
2 Turbos

Will update with pictures this weekend! But for now help me out with some aquascaping suggestions please!
