Exotic Aquatics, Parkville, MD
My travels took me past Baltimore today, so I stopped in at my old favorite, Exotic Aquatics. I wanted some fish that I knew they had, and their stock has always been healthy for me in the past and their prices good, so it was a no-brainer.
I asked the clerk what they do when they notice sick fish. He said that besides quarantining them they cull the weakest and sickest looking fish, dissect it and examine its gills and guts under a microscope, and then treat accordingly. I'm sure they don't go to that hassle for the obvious stuff like ich, but I feel good knowing that they go to such lengths to keep their fish healthy. Maybe this is standard practice at good fish shops, but it sure isn't at the chains.
I've also found most of the staff at Exotic Aquatics to be smart and knowledgeable, which is really nice. Unfortunately their plants looked shabby, but you can't win 'em all.
