i have an old 67 gallon tank, its 36" wide, 29" tall and 15" deep. it used to be a water dragon tank so it has a fern, coconut soil stuff, half of a hollow piece of wood as a sleeping area, frog moss, a pond, temp/humid gauges, heat light and uvb bulb and branches. i have a reptifogger but its not making fog anymore.. i heard that you shouldnt use a light for heat, just for day/night cycle. i think i just need more frog moss and leaves and the food. do i put the flies on a plate or do they just crawl around? since i have a big cage will that make feeding harder? thanks - jake
