Are fish embarrassed when they fart?
It’s not as though they can hide it from the other fish – the bubbles are a dead giveaway. Even if they're really polite fish who swim behind a plant or object to let one go, the bubbles will still be visible. And if all the fish got together and farted simultaneously, would the tank turn into a temporary spa? And has this ever occurred, or is it something the fish only do when the family has gone to bed and all the lights are off?
