In a few weeks I was either thinking buying a 20H and vert it or make my own tank (Was thinking a 18x18x24, like an exo or zoo med. But I have a few questions. Since this isn't ever going to be an aquarium, does the thickness matter that much? My local glass cutting shop only has 3/16 glass, but it's really cheap (I could make a 18x18x24 for around 25$) Would this have a high chance of breaking? I'm aiming for a 20H vertfor a few reasons. thanks
