FWIW when I wanted maroons I knew their rep, and that did not stop me, I just took precautions, as in wearing gloves or my shiny stainless dive watch(she'd bite at her reflection, and not me, but it took a little getting used to her charging at it and not flinching!LOL)
They are pretty fish, and unlike my clarki's she was only mean to me, not my fish.
My Clarki's got mean w/ all fish when they matured/spawned, and that I would not tolerate.
Most clowns are going to show some kind of aggression or be territorial, especially as they mature and spawn.
