10 Fish will not chew up your couch. 11 Fish do not ever insist on jumping upon your body in bed at some bizarre hour before dawn. 12 Fish never bark or emit any other obnoxious sounds that wake up the entire neighborhood. Fish do not bite. Fish do not run about the house knocking down your expensive Ming vases.
Fish are so cool - they can just swim around for hours and hours.
Fish will never try to hump you leg. Fish are just there. They are very Zen. They won't run away. You never have to spend good money on leashes, chains or flea collars.
