I really am in love with the MrAqua 12 gallon Long tank but I would like something a little larger in capacity. Can anyone else help me to find something that would fit what I am looking for? I would like it to be 6 feet or less in length with a shallow depth and height. I would prefer it to also be between 40-75 gallons. The goal here would be to have a nice long display tank with maybe a 40 gallon sump. Also, if you think this is crazy speak up. Right now it looks like I may have to get a custom rimless tank built.
