I noticed an extra long filament on the right side of a mille that I recently put in my tank. It is near the base of the coral and only seems to come out for a few minutes during peak lighting hours and doesn't seem to be irritating the coral. Could this be a hydroid or is this just an extra long PE? Any help would be greatly appreciated!
