Hard to believe it but he is. I went away for the weekend ten days ago and when I came home his rear end and fin was white. I immediately changed his water and he seemed to get better as the days passed. He was eating fine and was not constipated.
Last evening he jumped out of his bowl, probably because it was to warm but I don't know for sure. I'm such a lousy care-giver. I thought I did such a good job these passed 17 months but I messed up. Now I am going to find a nice plant and re-plant it in his bowl in his memory.
