I noticed he has been floating near the top of the tank kind of crooked lately. He has problems swimming down near the bottom of his tank, too. I brought him upstairs to my bedroom and gave him his own light to see if that helps at all. The office where I normally keep him has been so dark lately with all these cloudy days and it gets so cold in there that even a tank heater has a hard time working. Poor thing still has an appetite, but he has trouble getting to the food. He's been with me since I was a sophmore in college, which has been about four years now. He's survived moving back and forth multiple times with me to and from college, he's had platy's, cory cats, and snails as tank mates, and he's been my little desk companion for so many years. I know he is just a fish, but I will actually be quite sad to lose him! Not a great picture, but here he was in his prime!
