How hardy are they? If you get a school of them, do they really live a long time? ( a school being like 7 of them)

In many cases, they tend to pick each other off over time, and a small shoal of 7 will end up as a pair. The schooling behavior is more obvious in a larger tank with larger fish. This causes them to school for safety. If they are in a fairly peaceful setting, they'll tend to behave more as individuals, and they can be nasty towards each other. They are relatively hardy but not as much as many of the other damsel species.
