I posted an ad on one of my local classifieds sites looking for 120 gallon tank. Today this guy got back to me and said he has a tank, thinks its bigger than 120, he said it looks more like 150g. He also said that it wasent a custom made tank, it has black trim on top and bottom. I can get it for $150 if i like it. But do they make 150 gallon tanks that arent custom made?
