Choosing and Caring For The Betta Fish

He up cycles the iMac by installing a custom fabricated 3.5 gallon acrylic aquarium into the inside of a gutted iMac, adds a Whisper 3i aquarium filter that he chose due to the ubiquity of the cartridges, and adds a rope light system that serves the dual purpose of lighting the aquarium as well as heating the water to a comfortable 72-78 degrees Fahrenheit.

The Apple logo that sits atop the iMac G3? That logo is where you feed your small tropical fish. The top of the case is easily removable when you need to clean out the tank, or perform water changes.

Harms sells the entire iMacAquarium for $299 and a Do it Yourself kit for $189 that includes all the hardware as well as an instructional video on how to go about converting your iMac G3 into an iMacAquarium.
So what can you put inside your new iMacAquarium? A dozen neon tetras? How about a pair of corydoras catfish and a couple of guppies? A single betta? You have a lot of possibilities, as long as you realize that the tank is just 3.5 gallons, less when you add gravel and a few plants. For more information, visit
