I'm trying to make a vertical 10 gallon terrarium but its not working out. I have an aqueon 10 gallon tank I went to Lowes to get it cut to the size I need but I ended up measuring it wrong and the piece came out cut short. I keep measuring it to the same size but I'm not really trusting myself right about now so i'm asking what measurement you think the width would be for a regular 10 gallon?? Thanks for viewing/watching!!!!!
