Dwarf lions, scorps, dwarf angels, bristletooth tangs(tomini, kole, etc), marine betta(grouper like), one spot foxface(too big for my taste), Canthigaster genus puffers and the mimic saddle puffer. There are no groupers for a 120g.
I wouldn't put a fish that gets a foot long and likes to swim in a 120g. But this is also a fish I have never seen offered, so I imagine it doesn't do well in captivity.
