Out of character fish behavior

[tayyybra_]

I'm just generally curious. Has anyone ever kept a fish that behaves completely different than what it's "supposed" to behave like? Like everyone else's experience is 100% different than yours? If so, what fish? And how?

I seem to have my first "out of character" fish. I have a randomly super aggressive yellow coris wrasse.

I once had an adult size Purple Tang that was the biggest baby-- so easily spooked, and always running to hid. (And "No", he wasn't raised in an abusive household. Lol!)
