I run a LFS in niagara and i can say that it is very hard to find those little devils lol. The danios are nice also but i do know of a company that gets some weird stuff from time to time. The company is call A-Quality in Missasauga i believe. They are a whole sale place so i would imagine you would have to have them ordered in somewhere but they revolve stock so often they are bound to come up sooner or later.
I have gotten some pretty weird stuff from those guys that i couldn't find anywhere else. Hope this helps
