im not sure it saids moderate but i heard others have them in there reefs and it doesnt do anything
but all fish r different i think u should do a trial and error
or if ur lfs is like mine
they can put a fish in a certain tank for a minute and then take it out
Generally, they are IMO, more likely to pick at worms, small anemones and clams more so than corals. But never any gaurantees with any fish as to how they will act...Are safe with Cleaner shrimps and most should allow themselfs to be cleaned....
