So i started to keep a bumblebee PDF as a first time owner and wanted to turn a 10 gallon tank into a tropical vivarium. My thing is with the lid, can i use a plain clear custom cut glass as a lid? i've read that dart frogs don't need ventilation and other posts saying that they do? my plan is to have the whole top covered with a piece of glass with light on top (those fish tank lights). the thing that concerns me the most is that if i do completely cover the top, wouldn't that cause mold and mites to pop up in the tank?? any way to prevent this? any help is greatly appreciated thanks.
