then i stand corrected.... sometimes my hatchling tubs get this as well,,, but not every one of them at the same time. and the only time my adult tubs look like that is if they spill their water or something. everyone of theirs are dripping with condensation... so what this tells me is that the basement isnot properaly heated and the temp from the flexwatt is making this hapen..
i wander what their temps are in the tubs... id bet my right that their cool sides are in the 60's KY is cold right now.
