Well, I was cleaning Hades tank today, and put him in a cup so that I could do it more effectively. I wasn't gone more than ten minutes, but when I came back, the cup was empty. It didn't take long to find him flopping on the ground, and I quickly put him back in the cup. But I guess it was too much of a shock for him, because he swam on his side for a while, then sank upside down to the bottom, gills flared.
I tried to get him going again, but couldn't. The cup wasn't even half full! I have no idea how he got out. . . *sigh* I feel so bad that he's already gone, I had him barely a month and he was really starting to shine.
Sorry I couldn't keep you with us longer, but now you can properly rule over your land of the dead. . .
