Yes - so long as they don't come out for fun on the floor together, and they don't have line of sight of each other all day every day.
Best solution is to stack the tanks so the male is in the higher tank , and the female is in the lower tank, you can enjoy watching their antics when the boy see's the girl in her tank when he's on the floor , he's display by headbanging at her and trying to court her (especially in season) while she'll either "play hard to get" and ignore him and be cool as a cucumber , or she'll do the armwaves and press-ups and slow headnods back to him if she fancies him.
Best not to let them be out together , as the boy will be on the girl like greased lightning and wanting to mate with her..
If you adopt the boy, strict quaranteen for him from her for at least 3 months (no physical contact) and you need to use F10 handwipes if you have handled him before touching her or her food or any of her furnature (to ensure you do not pass any nasty parasites, bacteria, viruses, or fungi spore from him to her.
