SPS or other species that will do well in a 20 Gal

[Plantbrain]

I'm looking for some ideas for smaller species that will do well in a 20 Gallon tank.
I'm looking for color contrast and textural differences, minimal infighting.

Tank:rimless

4x24W ATI lighting, good PAR readings. A number of different bubs types I can switch in/out. Vortech MP10, 15 Gallon Sump Refugium which is well cycled and growing well. Filter cycles about 200 gph.

I do a 40% water change once every 2 weeks. Basically drain the sump and add back to that. Mame Overflow skimmer, Bag filter etc.

Looking for a collection to add that does well over time, I have few issues picking, cleaning, fragging rock and the like.

Any list or links are fine.

Are you necessarily looking for sps? If so most should do fine with you your equipment. I keep a mixed reef with softies, lps, sps. Acan lords, millepora, montipora, duncanopsammia, and zoanthids are amongst my favorites for variety of growth form, color, and movement
