Which would require a chiller to maintain... and no one's going to go to that trouble or expense just for a 6 gallon tank.
YWG is on the large side for a 6 gallon IMO
, although some will probably disagree. Check out Stonogobiops yasha and Stonogobiops nematodes, as either of these stay smaller and are fairly sedentary.
Totally agree that damsels would kill each other. I can't think of any that stay small enough for a nano tank anyway.
