  Great question! Patterns are definitely important for the fish’s lifestyle. Many fish have patterns for camouflage or so that they can recognize other fish of the same kind (this helps with finding their community and mates). Some organisms (not zebrafish, but something called cuttlefish) can even change their patterns dynamically in time!
