I can't find anything on this antibiotics on Google. @Humblefish have you heard of it?Yes I believe it does, it is to us, a zpack. But i believe it can be found in liquid form.
I would be curious about levaquin but i dont think it can be found in a liquid. Cipro however is just massivley harsh, where as i dont think the fish would have as much chance at an adverse affect with azithromycin
