wait for the hating comments to commence "What a waste of a tank"I have four Goldfish that are growing past eight inches long who live in a 75 gallon fish tank. But right now I'm in the process of finding my lovely pet Goldfish a 220 gallon tank but if a 360 gallon acrylic tank pops up I'm going to claim it for my four Goldfish.
If you have room in your house for a 125 gallon tank and the tank is in a basement on a cement floor then you can easily put in a 180 or a 220 or even a 300 gallon. A 180 gallon tank is only two feet longer and six inches deeper and six inches wider then a 75 gallon tank. While a 300 gallon tank is only twice as long as a 75 gallon fish tank.
LOL.....it's coming, get ready for it
