i had this posted in the general forum and only got 1 reply that didnt really answer my ?s i am new to corals and bought a zoanthid (green) sun. after floating the bag for 20 mins or so i placed it into my tank (30 gal). almost immediately after placing it into my tank i noticed strings (dark red,green or brown in color ,youll have to pardon me im color blind) floating throughout the tank, i mean hundreds of them. they were all about 1 - 1 1/2" in length and very slender. they seemed to be everywhere, like a thousand of them all at once. my skimmer cleaned them up in about an hour. the same thing ocurred on tues. when i did a 25% water change. am i doing something wrong or is this a normal thing? the polyps have not opened since placing it into my tank. will my zoanthid eventually open and survive or is he a goner? thanks in advance for any help you can provide.
