How does everyone go about their new fish when they recieve them via Vendor, LFS etc..???? I kno to leave them in the quaratine tank for at least 2 weeks which i have been doing but havent had to treat any for dieases(knock on wood) all look good.. Should i treat them new fish even if the look healthy for the sake of my other fish?? how do i go about this situation have 3 fish coming next week and wanna be fully prepared..
