I'm glad to hear your boy is in good spirits and seemingly healthy. I hope he continues to get better and better in your care. My only recommendation (ie what I would do) would be to monitor him for at least 2-3 weeks (both for the RI and rot) just in case either comes back. Better to zap it from the get go if it comes back then to think it's all good then one day have him come down with the same symptoms again. Good luck
