I've got my first colony of Zoanthid polyps and they are doing well, starting to expand already (faster than I expected). I was feeding them last night and I saw my first bristle worm. He seems to be living under the Zoa. Do bristle worms move about the tank, or should i attempt to move him to another location in the tank? (or just catch and remove). The only negative I've seen is as it was moving for food the Zoa polyps were retracting (which is what drew my attention in the first place).
