Hey guys so last night i took out my fire and ice zoa and dipped it because i saw 3 or 4 feather duster worms on the frag plug. I dipped the coral in revive dip and tried to manually remove them with a tweezer. I got 2 of them but there is still 2 more. Im wondering if the feather dusters will slow the growth of the zoa or cause them to close. Many heads stay open but a few close up throughout the day. I attached a pic pls advise on what i should do all my other zoas look great and there all on the same rock just seperate frags. Please lmk what you guy think and if the feather worms will hurt the zoas or not. Thanks
