Sad fishy news

My coworker's fish passed away during the night last night. I really thought he was going to make it.. But at least it looked like he was not distressed in his final hours, he looks just as he did when we left him. I took him out of his tank and put him in a cup and put the cup in my office so my coworker wouldn't find him. Even though he's dead, and I know he's dead, I still couldn't put him in a cup without any water in it. That's more unnatural than being dead.
