It does have the support on the top. I have it on a metal stand with a wooden board in between the tank and the stand because I have heard of them bottoming out. I just wanted to make sure if it was normal and okay for acrylic to bow some. Last tank I bought was a 40 gallon breeder without the center brace and the slight bow drove me crazy. I eventually took it down and bought this one because the stress was just too much
