While I agree that antibiotic resistance is a serious health threat, I 
don't want people to panic and think that by using erythromycin in their 
tanks, they are going to catch some horrible disease such as Staphylococcus 
aureus or VRE (Vancomycin-Resistant Enterococci) which have received a lot 
of media attention.   The pathways through which erythromycin resistant 
cyanobacteria could transfer that resistance to other gram-negative 
bacteria are quite complex. Using simple common-sense procedures such as 
simply washing our hands thoroughly after working in and around the tank, 
we can reduce the risk of any type of infection.

I'm not trying to condone irresponsible use of antibiotics; I just don't 
want people thinking that if a family member suddenly develops some kind of 
infection which is not helped immediately by the standard antibiotic 
treatment that the fish-tank is to blame.

If anyone wants further resources on antibiotic resistance, let me know.
