I want to get a pair of croc skinks and already have the enclosure ready but noticed that during the summer months the temp is 7-8º F higher than the max recommended in care sheets and tays like that for a month or so. I don't have A/C so i can't lower room temp. Any advice on how to lower the temperature? I've read that putting ice cubes over the screen top will help lower temp. but i don't think i can rely on it. If not, any suggestion on any tropical ground dwelling reptile that can live in a 55 gal. tank? Would probably buy next year or latter so i have time to research all options given.
