looking into a basilisk

[mmarchl23]

So I've been doing some research and keep finding 4x2x3 as a general enclosure size. I know these are high energy animals and can poentially hit 3'. The size suggested seems small to me I do plan on going with a 4x3x4 but I just want to be sure this would be an appropriate size. Any input on cage size or other tips would be amazing. Again I'm still just in the research stage and probably wouldn't pick one up until at the earliest june so that I can have a set up built and running.
