Get this little guy to the vet ASAP because I can almost guarentee you it's a respirtory infection. Until then, up the temps in his enclosure. This isn't something that will go away...but it will most likely get worse. Soon you'll have gaping for air and bubbles. My baby carpet python had an RI that I found early, and I had to give it injections every 2 days for a few weeks.
