Well, I picked up my new-to-me tank yesterday. The previous owner didn't drain it until I got there. 1.5 hours later, the tank was on the Uhaul on the way home. When I got home, I noticed the internal overflow wasn't attached very well. I gave it a tug and it cam loose from the back wall. Low and behold, a clown fish popped out. I scrambled and set up my 10G QT tank. So here he/she is. I already have two that are perfecly happy in the anemone. The previous owner said he dissappeared 9 months ago. So this little guy was living in the internal overflow for the last 9 months. He appears healthy and is eating well.
