glad you said that thats what we were thinking, we were going to use our old piranha tank which we were going to put on its end and that would make it 5foot tall 3front to back and 3lenth and mesh down the side which was the top of tank but we found it would be 2hard to do with the heating lights, draining ect, so as my dad has the skills we decided to build one but wasnt sure of disigne but you've said what we were thinking, havnt read the thing you sent yet had a quick scan it looks good is it for an adult size? we're going to look at a chameleon next sunday ( just look as we're not ready for him yet) he's 7months old so he wouldnt still need a smaller set up would he? thank you again its nice to have some one answer me. x x
