I would sell the tank if I could and build a 4X2X2 melimine tank
then you have Soooo many options
clawed lizards will scratch acrillic it may not be deep but its deep enough to make 1000's of little white scratches
If you cant sell the tank and want a snake you could get a Corn, King, Ball python ,Hog nose, childrens/spotted python, milksnake
Thats all I can think of off the top of my head
