Despite many fish of the same species living in peace and harmony out on the reefs, they don’t always place nice in the aquarium environment. Fish like chromis, for example, often shoal together above coral heads as a way to defend against predation, but in captivity small groups can dwindle to just one or two individuals over time. In ultra large aquaria, these fish might do very well in large groups, but in your average tank, expect community fish to quarrel to some extent.
