Fish school in my tank! LOL
But they have to avoid being eaten by my 10" grouper
(He has eaten a few in the past month)
I think your right on about why most fish don't school in aquariums. I had some chromis before the grouper and they used to fight constantly. After adding the grouper, the chromis have stopped fighting and school along with the damsels and coral beauty. They really stick together now in a very strange looking group! No more aggression once the predator was added.
