I bought a 55 gallon tank for 25 bucks from a friend and used it for a Chinese water dragon lizard for a while. After he moved on, and I moved out, I wanted cool fish for the tank as I got a whole bunch of stuff with the setup. The kicker was a Petco by my house had a grand reopening with damsels for $1, so I scrambled for some final setup and got 9 of them. Bunch of live rock, tangs, clowns, carpet anenome, and then a 125 gallon setup, I'm now down to a 12 gallon cube as we're trying to move.
Alas, the ups and downs of having salt tanks.
Long term goal of either reef or semi-reef once I get a bigger house and some upgrades for the 125. A coworker just turned me onto this site and today is slow, so I'm posting away.
