Yes - they're just not around any more. No one wanted the two pairs I had when I moved from Sacramento a few years ago. Traded bunches of them to Capitol Aquarium in Sac'to for 50 cents each credit...
They're really mild, not too prolific (small spawns) and not really brightly colored (especially when not happy), so between those who tired of them and those who lost them to too aggressive tankmates... that's probably why they're gone.
Hopefully Sam will circulate some fry when he can...
