Great start Eden, I was in the office all day and could not get this started, so here is my submission's, I will list what I saw the other day after visiting most of the north denver / boulder stores.
The one thing we should stress, this is NOT a review topic. As us Coloradans know
our LFS are very spread apart. This post is to help reduce wasted trips. I typically go to the boulder stores at least once per month, sometimes more lol.

Dwarf Neon Rainbowfish
They have several brackish tanks as well.
Special note: They can get just about anything you are looking for. Just ask if you do not see it in a tank.
