Too Humid?

i was wondering, cos i saw a pic of someone's tub , it seemed really humid, the lid looked damp as well...

so can too much humidity cause problems?

Yes, it can cause scale rot in a snake. The humidity should be between 50-60%. If you are seeing condensation then, it is way too humid in the tank!

I would agree that scale rot is a risk. Too much humidity will cause the bedding to become damp which will lead to the scale rot. (not to mention a major case of mold) It's just not healthy conditions in any case. ;)
