Oh this is sweet! I was really into aquariums before I got into pinball. I think at one point I had 7 different tanks set up. I'll have to look back and see if I can find any pictures. I had a nice 20-gallon reef tank with a few clown fish and shrimp, and my favorite was my discuss tank that also had a fire eel named Stewie and a Ghost Knife named Mr. Giggly.
My reef tank was my last one and my heater went haywire while I was gone on a vacation and killed everything, I didn't have the heart to start over.
