Reef Safe fish with caution can be generally considered reef safe, but you need to weigh that each of them have their drawbacks and that they will have their *asterisks* when adding them to any small to large reef tank. You MUST do your research before adding any of these fish as you will need to consider not what they might do upon initially adding them, but what they are prone to do in the future. Might you find a diamond in the rough that will not follow their normal grazing or feeding behaviors? Sure, but you will have to ask yourself, are you willing to take that chance?
