I was joking. :P No, no tank toppers! They'll just climb them and fall off all the time. I don't want to make one either, and there aren't any pre-made ones for 40 gallons that I know of.

I wonder if I'm being over-protective though taking Gizmo's hammock out. He climbs the chain and reaches the lid and climbs on the mesh lid, then falls with a thud, usually on the hammock, fortunately. Still looks like a potential injury.
