Glad the frog is better. We do try to be so careful but accidents do happen. Seems you have had your fill of accidents - I forgot about the leg cutting. You did a great job removing that cory from his mouth, and taking care of the cut leg. I can't imagine anything worse happening, my fingers are crossed that you and your little frogs will not have to encounter any more trauma - you've had enough for a life time! I would have been panicking!
Keep us posted and best of luck.
