Seem like every time I turn around I discover some new "nasty" in tank.
Noticed some dead areas on one of my favorite zoo rocks that is well covered with zoo's...a couple of days later, found these guys gnawing away on rock.
They have to have been in it for a long time as I have added no corals for months. Only thing I have added are starfish to feed harlequins. These guys have been hiding out well.
There is no question that they are eating the zoo's or at least killing them off by smothering them maybe
These are the only two I have found so far. Hope there are not more to come.
