Really need an advice. Although during a vet visit the vet said" airpipe and nostrils are free, no mucus or slime visible. Colour inside his mouth is great." And that there is no need to use antibiotics , because thete might just be a few little symptoms of RI because due the resettling stress and because his imun system might have gone down a little bit and in a few days all will be good - So after a few days when I left him alone just fed him one time I took him out today and I still can hear this crackling sound when I have him out. Not all the time and steady but I can hear it often enough. Still he has no slime or bubbles on his mouth or nostrils, he eats great and in his tube I can't hear this noise. What should I do ? I am concerned and fear that it will get worse when I do nothing against it. Would a beginning little RI caused of stress go away on it's own - through a rising imun system of the snake or will it untreated get worse ? I raised his temps to 88 and humidity to 86.

What advice could you give me ???
