Yeah i've heard that before but I make sure to clean it very frequently and put new water in it. If I get a jacksons or panther chameleon I am most likely going to get a fogger and sell the waterfall, not sure yet.
I live in Minnesota. My house stays around 70 farenheit (which will change if I get a jacksons chameleon) and i'm not sure about the humidity levels. Right now I have a screen enclosure from a previous chameleon but I can always buy a glass one so it can hold more humidity.
I just watched a video of someone unboxing a jacksons chameleon, and I noticed that their "fogger" was a humidifier with a tube leading into the enclosure. Is this the same thing as a reptifogger? Is it safe? Just wondering because I have an old humidifer laying around which I could repurpose...
