Well ... Dorothy managed to hang on to life for two more weeks ... in a strange upside-down on-the-bottom-of-the-tank sort of existence. She'd wedge herself under rocks and stuff (at one point she even got inside the castle which had fallen over) and The Wife would announce "that fish is dead!", but when I would try to extract her with the net she'd swim back in. This pattern repeated itself every couple of days ... Dorothy would look dead, but then would start moving when disturbed. No more. As of last night Dorothy had assumed the "official" Dead Fish pose, floating at the top of the tank on her side. So Daughter #1 and I had a bit of a "fishy funeral" this afternoon. The Wife will be quite pleased. The rest of us are sort of sad.
