hi guys!

A friend of mine donated to me a lovely 40 gallon corner tank with stand. The problem I'm having is finding a good lid for it! It was a fish tank and is now going to house Rhyban, my florida brooks. I've got a makeshift lid on it that's secure enough, but it's very... well... ghettofab. Anyone know somewhere good that sells pentagonal terrarium hoods? Or if it's possible to jury-rig an aquarium lid into a good terrarium lid?

Thanks!
