Yeah 20L is fine for awhile but he is in that now and has zero extra room. I am building these cages myself, so I was thinking somewhere in the 3-4ft range for length, 2 ft wide and 18 in. high.
The herpguy name seems to have worked since I have a beautiful fiance, so wooing anyone else wouldnt be in my best interest, but thanks for the advice
I was told 20L would work for the entire life.. not sure though, since i've had mine for about a year. Height isn't that important, I think it would just make the humidity control harder. Unless you build a mister.
