Ok!! I don't want to sound like a Petco Supporter (which I am not), But that story could have been in any LFS in the world. Most if not all LFS I have ever been in have a multiple tank system, and if you look long enough I can assure you you'll find a fish with spots or torn fins on an infection or dead. I have never seen a LFS offer a guarantee on saltwater fish (unless you buy online). Also, the mandarin very well could have been eating Brine (probably not but maybe) At least you wouldn't have to worry about the mandarin catching ich (slime coat prevents it
). I was just amazed at the quality of the livestock in this certain store, I also knew I might start a firestorm.
