My answer to that would be very biased.... but check out the list of stores that support CTARS.
Your answer would also be true . . . (~_^)
In a lot of ways, LFS are at the mercy of their suppliers - if a supplier ships healthy fish, the LFS will have healthy stock this week. If the supplier ships fish with ich or flukes hiding in their gills, the LFS will have to handle that problem. Most of the proper LFS run systems with copper in them, but many don't - and Petco's corporate parent doesn't allow them to, so I consider ich a virtual guarantee from that source! I did have communication with a shop (not in CT) that's thinking about performing actual acclimation / quarantine on at least some fish prior to sale - it was like seeing a mermaid riding a unicorn in my experience . . .
That list of Sponsor stores? Those are folks who care enough about the hobby, the aquarium community, and the livestock to make the extra effort and do it the very best they can - and they're the go-tos in this part of the country.
