Check out the tank yourself at Shore Lodge in McCall, Idaho. Nice tank. Great small town with good restaurants, snow skiing, winter festival, snow cross races, and summer fun on the lake.
Total tank volumn is less than 1100 gallons less the sump capacity. There are two tanks in Boise at Pioneer Title Company that are just under 1400 gallons in volumn. They measure 16' × 3' × 4'. Idaho has some large private aquariums!
