That's some fancy woodworking on this 300 gallon aquarium!
The wood cabinet features an aluminum subframe for strength. The total dimension of the tank and cabinet measures 9 feet long by 32 inches wide by 6 feet tall, so the glass tank itself is likely 96x30x24" - very nice, functional, and aesthetically pleasing specifications! A full-length fiberglass artificial reef inset is included in the auction's starting bid of $9,500 USD, although we hope whoever buys this system decides to establish a living reef or planted aquarium instead.
And no, this is not an April Fool's joke
