So I wasn't sure where to post this but I have a friend who is going back to college shortly and asked if I could take a few fish off her hands so they wouldn't get stressed out. She asked if I would take her platys which I know get along well with Bettas for the most part (she also had them with a Betta). Two weeks ago (maybe a little longer or a little less) one of her tanks (the one with the platys) got cotton wool disease she quickly quarantined them all losing all that she had but 3. The 3 are still alive and are doing well and have been quarantined and treated for the past two weeks. Will they be okay to merge with my Betta now or do they still need to be quarantined and treated? Sorry if I rambled on but I'm suppose to be getting them tomorrow.
