I have the opportunity to get a Harlequin Tusk from a friend of mine, I know that they go after snails (None that i particularly care about in my tank) crabs ( evil little buggers), Shrimp (one cleaner shrimp and two peppermints), but what about echinoderms? I have an urchin that I have been meaning to get out of the tank, and a Sea Hair Nudi. in the tank too. My cleaner shrimp does nothing but sit in the back of the tank all day, and the peppermints were added to get rid of aptasia when i first set up the tank. So my Question is who is safe when it comes to the Tusk? If i go this rout i will be getting rid of the cleaner shrimp for sure.
