New Tank Needs A Lid.

[Camillemj]

I bought a 10 gallon tank from Petco, but it dosen't have a lid. I bought a peice of plexi glass and cut it to fit my tank then my light sits on top of that. My problem is that the plexi glass is bowing in the middle. Also like most people money is tight.

Does any one have any other solutions that they have used that work or other ideas. I'd like to hear anything anyone has. Thanks
