   Thanks Swagasaurus I know why fish shoal. Only think there is a difference living for millions of years in the wild or in captivity in a tank in which they've nowhere to go when afraid / "threatened" by "predators aso.
   Flight-behaviour in that case has everything to do with stress to me. I'd never add fish to a tank that make other fish show shoalingbehaviour for that reason. But hey, different opinions !!
