I have an alcove that measures 59" wide (long in tank dimensions) that I would like to put a tank into. If I had one more inch I could fit a 150g long in there but next to removing drywall on each side to make it fit I'm an inch shy. I know I could go to a 150g tall or any other tank with a 48" length dimension but I feel like I'm wasting space. Any suggestions on a good tank size for this area without going custom?
