Do goldfish have an impact on humans?

Yes, coming home from a hard day of -lets say work- nothing can lift your spirits more than having the inviting face of a pet goldfish come greet you. It is also important to note, that having an aquarium and spending time watching your fish swim around is a great way to get yourself to relax and/or relieve stress. The illusion of weightlessness brought on by the way fish swim is greatly responsible for this stress relief.
