Thanks for the (somewhat depressing) links, Justin.

Well as I read more and more, I am faced with MANY possible culprits and none that seems exactly right. Yesterday the hawk looked much better, with the open lesion being all healed up and just a smaller bulge beneath the skin there again (more like what we first started with).

Can we talk about general medicinal approaches...
What product do you guys used for antibacterial medication for fish? Pimafix? Melafix? Any others? Karin, do you have a preferred medicated food?
