So basically to throw some pictures of what I described above. The first pic is of the corrugated plastic cut to size, followed by the vinyl tile that was laid over the corrugated plastic. The final picture is of the new cages (top) over the ZooMed kit cages below.
I plan to get some more plants in the enclosures. As of right now, the larger (18x18x36) enclosures have my Xanth pair (separated) and my Jacksonii pair (separated) are in the old enclosures below since they are currently significantly smaller.
