Hey fellow mfkers, I was wondering what is the smallest volume of water for a 6 feet tank you guys have seen or heard of? I was just wondering because I currently have a 60 gallon in my bedroom in a two story house. That is about 900 pounds sitting in the corner of my upstairs bedroom, my friend tells me it's a bad idea but I think it's okay. Kinda wanted to upgrade to a 6 feet tank but don't wanna go overboard since it's going to be in my upstairs room. Was wondering if there are such things as 60,70,80 or 90 gallon 6 feet tanks?
