Here is the deal. I'm new to this and I have a 10 gallon tank with a venus fly trap. It started off nice. I have perlite on the bottom and then I have some mixed with with some peat moss. Then I have this long fiber moss stuff on top of that. I filled it with about 1 gallon of distilled water and put a fluorescent light over it. I then fed it part of a night crawler and then it started to turn black and looks like it's drying up. I spary it with the distilled water everday and I even put a second light on it but I dunno. Should I cover the top with some plastic to help out humidity or what? All the traps are closed and they look like they are cracking and turning black. Can anyone help out a rookie?
