I was just wondering how many tanks people try to keep up with? I always have had a freshwater tank on and off for as long as I can remember, but when I got my first saltwater I'm always looking for an excuse to get another tank. Right now I have a 55 gal and 40 gal reef, a 29 gal with live rock and a few shrooms, in the process of setting up a 135 gal FOWLR, and a 5 gal freshwater. I joke to people they can come over and see my tanks @ $5 per person.
