I think that quaranteen or in stores is about the only place where UV
has significant utility. Yes, fish are tremendously stressed when
transported, and the cross section for a shop to get a seriously sick
fish is large. (Translation... if you get in thousands of new fish a
week, you are going to run a higher risk of introducing a pathogen into
the system than a home aquarist. For example, it has been... I guess
over a year since I've added a fish to my aquarium.)

UV will tend to degrade antibiotics, although the rates vary.
