I have 2 tiny hermits.....i havent been paying much mind to them but today i was noticing one going on my Zoa's and picking at them and disturbing them alot.Are they troble for my Zoa's? Will they eat them?
Sometimes... It's pretty rare that they'll eat corals. Most of the time, it looks like they are, but they are just picking off algae from between the polyps.
