Much too small, yes. That's quite a range of options you're throwing out there - go with the MH over the NO I would think, for starters.
I have a 29 with 2x55 PC over it - barely bright enough. Supplemental feeding, supplemental natural daylight, etc... And a pair of Ocellaris clowns, and one other tiny fish. That's about all. Certainly no TANG...
You're really limited in this size range, unless you put a lot of resources toward filtration, and maybe a sump.
Nice thing about the 29, it has no center brace, so a single MH is an option.
