At a yard sale I found a tank for only $5 and I bought it as Akuma (my corn) is about 16 months old and is ready to move out of her 10 gallon tank. (I have talked to a reptile expert before I bought her and she said a 10 gallon would be fine for a few years as long as I took Akuma out about every day for exercise). The problem is that the dimensions are length: 30.5 in, width: 12.5 in, and height: 19 in. Is this ok for a corn snake? Akuma loves to climb and the new tank has a larger base area than her current tank. And the tank did not come with a lid and I'm not handy with creating things, so I need to buy a top before I could move Akuma in (I have already cleaned and disinfected the tank). I am just having issues finding a lid online, and I can't think of any other way of finding a correct sized lid without the tank. Any suggestions? Thanks for your time. If I do end up having a problem I will probably just buy a new tank including a lid at the nearest reptile store. The picture is her from three months ago.
