Hi. I have a six year old african clawed frog. About a week ago I caught one of my bottom feeder fish sucking on the frog's back. Three days later I noticed a black ring on his back (where the fish was sucking on him) and today I noticed that the ring turned white. I went out and got a little infirmary tank for him and currently he's being treated with T.C. tetracycline ( tetracycline hydrochloride) for freshwater tanks/fish. It's one of those antibiotic powders you mix in the water.

The white stuff/circle is indented a bit. It appears to be a gash in the frog's back. He is moving a lot and at the moment is swimming fine.

Does this sound like the proper course of treatment? I'm including some pictures of the injury. How long should he undergo treatment? Should I keep him in there until the white stuff goes away?

Thanks.
