Headband Humbug
Dascyllus reticulatus
One pattern that is constant throughout human history is the concentration of wealth and its redistribution.
People strive to get rich.
I believe this behaviour is an instinct. The reticulated Damsel have a hierarchy in which certain individuals are given access to the best plankton and mates & they fight for this access.
Intelligent as we think we are, we still behave on instinct, we still act like fish.
