ok so here in my town theres three pet shops. theres one the next town over im visiting later today and theres two aquairums then NEXT town over from that.
The first shop i wont even BOTHER taking a pic inside -shudders- the shop is PUTRID, BUT even though its COMPLETE mess and the tanks are pretty filthy she has good know how. granted i saw three dead and two almost dead bettas there today ( :( ) shes making my tank (if it is made badly my partner will refuse to buy it) she is nice, and she is part of aniimal rescue group to home cats and kittens and dogs and puppies...theres a kitty there i want but we have a cat already :(
the second is cleaner but horrible. they are always rushing to get you gone and they WWWWWWAAAAAAAAAAYYYYYYY overstock the tanks. not to mention they were feeding ALL FISH (both fresh and saltwater) pond flakes.... they put 30-50 OR MORE in each tank. their salt water sections sinking and i would HATE to be there when it collapses.
i snuck a pic of the "Betta" section, you can see all the lovely bay tanks holding plants but NO BETTA GETS PUT THERE AT ALL. the Bettas are housed in the takeaway containers then tipped into a bag when purchased (mind you they are rough as guts in transferring the fish as well)

the females are kept spred in three different tanks depending on their type. the males are there abouve the bays and three piled high on a light around the corner on a plant tank.
the last one is where ive bought ALL my fish so far. they are clean, happy to spend 45 minutes talking (whups!) and always rush to dispose of deceased (on the rare occasion ones dead) fish.
here is the housing of the male bettas:

two of these sit side by side
the females are in a community tank.
what does your LPS look like???
