This modern fish tank is called the Modular Fish Hotel, and is admittedly as practical as it is stylish. Thanks to a flat top, you can stack stuff on top of it – including other Modular Fish Hotels, to create a Modular Fish High-Rise. Just keep in mind that if you try to fill the tank with Pabst Blue Ribbon, your fish will still die. They aren’t that hip.
The Modular Fish Hotel comes in either black or white, and is available only online, from Urban Outfitters. Regularly, it sells for $45, but it is currently on sale for $40.
