We decided on our beardies and will hopefully be getting the rest of the stuff to build the enclosure tomorrow. I am still a little worried about how the fixture sits and if it should be changed to house an MVB in the Crossfire enclosure. Here is a link http://www.freewebs.com/crossfireenclosures/. I am worried about the distance being fixed with an MVB. If I cut a hole in the top, it becomes a pain to make it bug proof, but then I could raise and lower the MVB as needed. I could really use some advice here. Thanks
