This may be a weird thread, but what are acros you think look good with no to minimal polyp extension? I have a dwarf angel in my 90 gallon, and the acros in there are colorful and grow decently well enough, but never have had polyp extension since I added the fish.
Hawkin's echinata and Red Ferrari look pretty good, imo.
