I had one that was this size for my 20 gallon long, It along with the lamp I had worked well, but without the screen top and glass (not holding heat well) the heat pad should be sufficient. I think 11"x7" should work. I wonder if Petco carries Cobras? I will look on their site in a min. If so I will just buy them there, with shipping charges it will add up to the expensive Petco prices anyway. Thanks.
