Shouldn't be an issue.

The Vomeronasal organ (Jackobson's Organ) that processes the (smell) of prey in the room, doesn't have the range many people often believe it has. You will often see your ball python, when its hungry stick its face in the opening of holes, or hides in your enclosures trying to pick up a 'scent'.

Similarly when dangling prey into your tub or tank, you will notice the closer you get, *then* the snake starts to stir and pick up on it.

Housed even in the same room, there shouldn't be in issue. Right next to each other? perhaps*, and only then... perhaps.
