What you have is a respatory infection...First off,,,you need to isolate the male NOW!!!! Get him away from all other snakes..Second,,,crank the heat up in the females cages...Since they are not showing the signs yet,,,pushing the heat up about 5-8 degrees may help ward off any further infections...Once you have this done,,,TAKE THE MALE TO A VET!!!! The vet will probably give him medication called "Baytril""...R.I. is extremely contagious,,and FATAL,,,if not taken care of immed...Another thing,,,you can crank the heat in the males cage((ONCE YOU ISOLATE HIM!!<img src="http://www.faunaclassifieds.com/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt='

'>,,and give him about 2 days to see if the R.I. clears up...If not,,,,he needs to go to a vet,,or he will die!!!! R.I. is a dangerous disease,,and can wipe out everything you have...If you just recieved these animals((2-3 days ago)),,i would call the person i got them from,,and demand a refund..Do ot send them back until they are cured,,chances are that they will not survive the return trip!!!! One more thing,,,R.I. IS AN AIRBORN DISEASE,,AND WILL TRAVEL!!!
good luck
