I am getting about a 64 gallon aquarium that is going to be a temporary home for Frogger while we build his even bigger and better home. It was only 10 dollars and I dont think it comes with a lid. This is the figures (24 x 13 x 48) in I was given. How can I make or where can I buy a lid for it?

The guy said it had a crack and wouldnt hold water but it is all together and stable. I will probably get some aquarium sealant and make sure it wont come apart.
