That's interesting! They might also evolve a tendency towards moving to the left flank of the fish.

    I guess they swim in the direction of the majority which is probably always the same in a circular tank with many fish.

  Reminds me of the evolution of fish that prey on scales of other fish to have two distinct types with the mouth on the right or left: https://en.wikipedia.org/wiki/Perissodus_microlepis https://en.wikipedia.org/wiki/Perissodus_microlepis Depending on which type is more frequent the other is more successful because the prey is more cautions on the other side... edit: spelling

    My comment was half in gentle jest, but you have really found a relevant example there - thanks for sharing. I guess I have a potential PhD project if I ever want to get into maritime biology: "The Dark Side of the Fish: How Crafty Parasites Outmaneuver High-Tech Pest Control"
