I have looked for a ready available canopy, for the size of tank. I failed on locating one.I have a canopy from R&J Aquatics. It is called the Xtreme and is a 15 inch canopy. I suspended lights on a bridge with brackets inside canopy top (just 2x4 with brackets I made). I can adjust lights on suspension cables inside the canopy. I call easily pull out bridge of lights to change bulbs. If you want you could also mount lights on the canopy lid, but then you could not adjust the height of the lights over the tank.
