If you can get some Tylan(tylosin) from a feed store or Tractor Supply and put it in the water, that will help. They do need oral Baytril though and for about 14 days.

To help the male, who probably won't make it if he is open-mouth breathing, put him in the bathroom, close the door and turn on the hot water(shower) full blast. Make it very steamy in the room and leave him there for 30 minutes or so.
