Yup, like everyone says you prolly want to quarantine for at least two weeks before adding them to the tank. I currently have ten girls all from different petstores sitting on my kitchen counter in a random assortment of containers for theirs. Some are in cut in half tea/juice jugs, two are in vases, and a few others are in tupperware containers. I'm doing daily water changes and in... another 11 days (bah) I get to add them to the tank. :)
