Hello and welcome to FF! More on quarantine in here: http://www.frogforum.net/general-dis...uarantine.html and http://www.frogforum.net/general-dis...ing-frogs.html.

Keeping quarantine enclosure in a separate room if available is a good idea, because some pathogens can travel through air (i.e. fungal spores). Never share anything (water dishes, feeding tongs, food dishes, etc.) between enclosures and do not return uneaten feeders to a common bin. Wash hands in hot water with soap between handling chores in different enclosures or wear disposable gloves and do replace them between enclosures.

Do not put all frogs together until a minimum 30 day quarantine with 2 negative fecals conducted 2 weeks apart are done. Good luck !
