Robyn, it wouldnt hurt for you to investigate all the fish stores in your area. Look at the fish and make sure they aren't overcrowded. Make sure the store is clean and the tanks are clean and don't have a strong fishy odor. It can be a daunting task, but looking at all the fishies is fun and you can learn a lot by talking with knowlegeable fish keepers. When you find a LFS you can really trust, the isolation (quarantine) can be a little shorter. Try not to buy your fish at a place like Petco or Petsmart if you can avoid it.
