Should be fine. Mine got sucked into a koralia a few days after introducing it. The surviving nem is about 1/4 the size of the original, but it pulled throught fine. My larger piece that did not have the foot on it did not make it. I believe that when a nem is "chopped up" like that it releases a lot of nemocytes, and can harm live stock in the tank. I did not have that problem, but another local reefer said he lost everything within a few days of his mis-hap. Maybe someone else has input on this. Good luck
