I've always had plastic hoods on my fish tanks. I recently have decided to upgrade my tank equipment and purchased a Hagen T5 HO lighting system. It's not possible for me to suspend it from the ceiling so I'm currently using the black plastic holders that hold it above the tank. My problem is that I also purchased a standard glass canopy but it won't fit with the light holders. Is there are special type of canopy that I can buy that will work with that system or can I go lid-free? My tank has glo-fish, amano and red cherry shrimp, and panda cories. I plan to add a small school of neons in a few weeks.
