I have a 140g (5 ft long) and have had success with mixing evansi with dispars, ignitus, and carberryi. This is my tank last year:

SPS didn't survive long term with all my angels and I have since reset my tank with just anthias and chromis.
I currently have a mixed group of evansi, dispar, randalls, ignitus, and lyretails in my 140g now.
