I have had this Candy Cane in my tank approximately 3 months and it was doing well until a few days ago. It appears something is eating the heads and leaving a white tube behind (see picture). Any ideas on what this could be or how to fix? The far right two heads are dead and the "worm" appears to be eating the head with the arrow now.
