My first clue was the monti's. The setosa went from bright orange to pale orange and covered in slime. The bulletproof orange cap did the same thing. Zoas closed up, acros rtn'ed.
BTW, it wouldn't have likely bit me, since I always have on dry, rubber soled shoes when working in the tanks. Since it couldn't have completed the circuit using me, I most likely wouldn't have even felt a thing. The corals were what clued me in that I had a major issue.
