i have a 20 gal tank with a running waterfall so the humidity is always very high, the problem i have though is that this creates a constant build up of condensation on the glass, i wipe it down every day. is there a solution to this problem?
You might have to get a fan, I have the same thing going on in my Pacman viv where I have a waterfall. The condesation is like a trade off for the humidity, it sucks but at least we know our vivs are humid.
Try letting it be for a couple days. When I clean the glass everyday, condesation builds constantly. If I leave it for a day or two, a thin layer of film builds, and the condesation goes away. It doesn't look as clear as freshly cleaned glass, but much better than the condesation. The fan is the best way to go, but I haven't gotten around to doing all my tanks yet.
I am not sure how much experience you have with darts so I am only going off your join date. When I first started I didn't like the condensation either because it wouldn't let me see into the tank. I wiped often but I also noticed that I didn't see them as much as if I left it for an extra day or two.
Like stated before leave it and eventually a little film will form and condensation wont be as much of a problem. And don't quote me on this but the condensation has more to do with your outside of the tank temperatures. If they are about the same then you will notice there doesn't seem to be as much of it.
I would say just leave it alone. From my experience it seems to make the frogs feel safer.
