I had to add this because its too funny. She's still playing with the heater today. A few months ago, we had a heater malfunction in another tank and it almost wiped out the entire tank. It really freaked my fiance out and, bless his heart when he gets nervous, he drives me crazy. It is pretty sweet though. He never had any interest in tanks or fish until he started helping me out. He's been home and hour and, because she's swimming around it, has checked the water 5 times in that hour to make sure she's okay.
