As with any medication, over use or broad indiscriminate use can lead to resistant strains of the diseases these antibiotics were meant to treat. It's what is happening in the meat, poultry and fish industries in the U.S. People are being exposed to antibiotics through the milk they drink, the beef and chicken they eat as well as some farm raised fish which is making it harder to cure humans of "simple" disease that, in the old days, a single shot of pennicilin would have cured. The issue with fish and fish tanks is that it is through these that the resistant strains are also being created and infecting people. So should antibiotics be so readily available to the average person just because he/she has a fish tank? HOWEVER, I've saved a number of fish using antibotics so I use them when called for but I use them only when called for and not in a " just in case" scenario. Should I have to suffer the loss of a fish pet because of someone else's irresponsible use of medications? I am very disappointed at what medications I can no longer get. Some of which I know were "miracle" drugs as far as I was concerned. But I understand whats going on. It just sucks!!! But this is why keeping a healthy tank is more important than ever because the "cure" for most problems is prevention. A healthy tank, properly stocked and maintained, will help prevent many diseases in the long run thus eliminating the need for medications.
Sorry, I think I went off tangent.
lol I hope I made a good point.
