This has been my experience. As I said, I have hundreds of them, no issues at all. They will eat algae off the base of any receding coral, but do not eat healthy tissue. Mostly found grazing on algae on the glass when I forget to wipe it off for too many days. Found mostly on the rocks, I find they do a great job at keeping my rocks clean. For me, I would intentionally introduce them to a tank.
