Fish's grievious bodily harm.

My brother admitted to me yesterday why the fish is really sick... The story goes that he tried to scoop the fish out to clean its tank without using the usual glass dipping technique. Instead, he grabbed the fish in his hand and the little beggar slipped out and suffered a three foot drop to the hard floor. After moments of panic Andrew managed to pick the panicked fish up again, only to repeat the trauma with a second slip knocking the poor thing senseless. It's never been the same since. I fear no amount of peas will fix poor fishy now. Poor fishy.
