Hi Mikaila31
I've never seen them at any lfs I go to, but once in a while they turn up on AquaBid.com.
When I see them at auction, I'm tempted to buy them, but since I would want to be certain that they are actually eating and healthy before I bought them, I never have.
IME, the healthiest fish we have gotten off the internet were from aquabid, just make sure the seller is good
