Guys, you do know that almost all the box stores and your LFS get their fish from the same few places right ???
Segrest Farms is the main supplier in the US.
Tropical fish wholesale and Marine fish wholesale - Segrest Farms
So unless your fish are coming from a local breeder or from your club...they aren't magically different in a LFS.
Care and maintenance vary wildly from box stores to box stores and LFS to LFS. A big chain is not automatically a bad place. A LFS is not guaranteed better except in supporting a non chain business.
The reason stores can use a central system is that IF it's maintained properly there is a huge battery of UV lights sterilizing the water.
We once lost power when I was working at our local Petsmart. Employees stayed till midnight stirring tank water and adding peroxide to stimulate oxygen we saved 98% of the fish.
I have LFS that I'll never buy from. Lots of dead fish, poorly maintained tanks, etc. I'd like to buy from them but I won't.
Glofish have jellyfish DNA. They are not dyed. It is a GMO fish.
All of my current fish except my Pearl Gourami are from my local Petsmart. So slamming every box store because it's a chain is just narrow thinking.
My Petsmart Roselines are doing awesome.

If you have a store that you trust that's fine, be patient. Buyer beware of EVERY store.
