My 5.5 came without a hood...I ended up getting a piece of plexiglass cut at my local Ace Hardware to the exact size I needed...then with dads help cut a rectangle for the heater/filter to poke out and put another rectangle on a hinge (with a drawer handle) so I could feed him. THe light is from my moms old hex tank 10 gal (which I don't use anymore, to tall for my fish, I've found.) and reaches across the tank walls, so it's not directly on the plexiglass. I also haven't found my lights to give off heat.
