I'm not sure if these polyps are attacking my corals or not but the ones growing close to them seem to be receding slightly and I'm concerned as these polyps are multiplying fast. the strange thing is, i'v not added anything new to this tank in forever and these popped up out of nowhere and are spreading rapidly. They look like the common yellow polyps but are only 10% the size of those and unlike the common yellow polyps, these polyps retract into tubes like feather duster worms. Any ideas?
