Found some pygmy cories if you're still looking. Old Town in Chicago has at least 2, and Fish Planet has at least 3. Hope that helps.
We were hunting for habrosus with no luck, but did find some nice julii (?) at fish planet. Our solo habrosus has been schooling with, climbing on, and generally staying super close to the julii. It's kinda cute!
Sailfin pet shop in Champaign usually has them. Their shipments come in Thursdays I think. Call ahead to check on stock. Owner John is super knowledgeable and so is manager (?) Rachel. Their tanks and fishes are clean and healthy. Small shop but great things inside.
