Science! On the balance between “loner” fish and “social” fish within a school. Click through for the full article, then scroll down past the silly office game part to where they talk about behavioral analysis.

 

Each personality type gets some form of bonus when it’s rare, but benefits dwindle when the type becomes too common. If social fish are rare, just about any individual they try to buddy with will probably be a loner, prone to discovering new food patches.

Conversely, a loner fish should have an advantage when social types abound because types that club together fail to cover maximum ground, leaving plenty of food patches for a loner to discover.
