Is it possible to have a tank just sitting on the floor, instead of on a stand? My dad surprised me with a 65 gallon extra tall. I'm afraid that if I put it on stand I won't be able to reach inside of it, it's two feet tall and I'm only 5'1. Would this be too stressful on the fish? It would be in my room so not many people walking past it, but I do have cats.
