Yes Will. The same principal. If the original enclosure has not had any inhabitants, then it should be sterile. While you are treating the specimen, it is perfectly fine to keep him in an isolated, quarantine bin with damp paper towel as substrate. As has already been touched on though, you will need to completely disinfect this quarantine bin before re-introducing your frog back in. This has to be done every day until treatment is complete. At the completion of treatment, it is then safe to introduce your frog into it's permanent enclosure.
