I have kept his unusual death in the back of my mind for a long time, blaming myself for his being lonely while we were gone during the day, and for the gravel being in the tank, although the pet store recommended it. It might have been an accident, and guess I'll never know.

Letting go is a good idea, and yes, I do that a lot. Kicking myself for things. Heck, I'm still mad at a mama rat from the Univ. of Hawaii lab cause she refused to take care of her newborns and they died. I took her in to save her life. After all these years, letting go, whosh, like the wind.
