Shallow breathing question

[pmds]

I recently had 2 ball python hatchlings kind of... dumped on me. I have a number of my own snakes but these two were not something I was really looking for at the time, as they were not being properly cared for and I knew this would turn into a large project.

Step one, was mite treatment. They had mites terribly. I quarantined them both and treated them for mites, after the treatment and all the mites were gone I still had trouble getting them to eat. I took them to a local vet who force fed them and told me that if they're still refusing to eat to try that one more time.

I force fed them a second time, the following week. They're both incredibly underweight still. The newest problem is that one of them seems to be taking quick, shallow breaths.

Does this seem characteristic of a respiratory infection? I hear no wheezing and there are no bubbles around the mouth. The snake is breathing closed mouthed.

Any suggestions?

What temps and humidity, pics of your setup would help. do you have hides?

They're each being housed in a 10g right now, as they're fairly small. The warm side hangs between 90-95 and the ambient is about 80. Humidity varies from 40-45 on average. There are hides, and the snakes are spending the bulk of their time in the hides.

They're housed separately (from the mite treatment, and I try to quarantine all new animals). And they have nearly identical enclosures - but the one just seems a little off to me. They were both together in a 10g at the previous owners house, on gravel (x.x) with a grossly over sized basking light. I have no idea what else they did (or didn't do) to them.
