I recently upgraded to a 4x2x2 enclosure from Carolina Custom Cages, and for the first time I'll be mounting the UVB fixture inside of the tank instead of on top of it. It's not immediately clear how to do that however, so I'd appreciate advice from anyone who has a similar setup. The UVB fixture is pretty long (it's an Arcadia 12% 36in), so if I attached it to the mesh with wire twists or something then I wouldn't be able to open the top anymore. Is there a better way to attach it to the back wall instead?
