Kind of a loaded question ...
Many will survive - but again, color will brown out without lots of light.
I grew a nice chalice from a bottlecap sized frag, til it was too big for my 12-g nano and now it's a mother colony in my prop system.
I have customers keeping acros in nanos under PC...
Do I recommend that? No, not really - but they can and do, do alright.
Just don't expect tremendous color or fast growth.
