So I have a question about my chameleon getting the white dust around his nostrail. I know this can be caused by over supplimenting but I havnt givin him any suppliments for a couple weeks now and he still gets it. I read that reptiles can get this from not being wet enough. Could my problem be humidity. I got a Veiled because I read they are tollerable to different climates and humidity levels. I live in the desert and struggle to keep his humidity above 40 percent. So my question is should I get a waterfall to help with humidity and will this cure his white powder build up? any help is appreciated.
