I've noticed in my tanks that if I didn't change the water after a week, if looked at in a glare, there is a thin layer of just week old ick on the top of the water. With my water bowls I also have heat lamps over them to increase humidity. My water would probably be evaporated after 2-3 weeks.
I just found homes for my 4 snake ladies: ball python, colombian boa, hogg isle boa, and a burmese. *sniff* How I miss them so...
How do I set my laser printer to 'stun'?
