well i spent the weekend trying somthing different with my pac mans enclosure, i am still using the glass top, instead of using the plastic strip that fills in the void torwards the back of the tank, i took my screen top and cut a strip out to fill the void where the clear plastic stripping once was and i think i perfer this route, i havent had any problems with loss of humidity, and my tank is no longer a heat trap with temps in my terrarium now staying between 80 and 82 degrees, and im sure the extra air flow would have to be beneficial, my night temps are still about the same staying around 75 degrees on the cool side of the tank, outside of that i think im ready for my suriname horned frog and looks like it will be here wednesday, now that the heat is breaking around here, if anyone else has any advice on good temp for these guys, your advice will definatly be welcomed, and thank you everyone for the ideas and recommendations
