No, they should be housed individually. Pet shops generally don't have a clue.
I had a local reptile shop that had two WC males in the same enclosure. One was jacksonii xantholophus, the other jacksoni jacksoni. Both were at opposite sides of the enclosure, very dark & continually eyeing each other up. Visibly stressed & dehydrated & surrounded by feeder insects. And this was supposedly a specialist reptile shop?
