I have a chalice that is showing signs of RTN on one edge that is in the dark under a cave. I pulled it out of the tank and dipped it in Revive and broke off a piece of the dead looking skeleton. I returned the chalice back into the tank and noticed in the container with the broken pieces these stars. Are they bristle stars and no reason for alarm or something else? Come to think of it, there are several of these tentacles that pop out and I've never been able to tell what they are. I've never seen the body before until now. Thanks in advance!
