ok so some time last year my tank contracted red bugs and aefw. i figured i got rid of the aefw with a simple dip of the coral and it was not to be seen again. the red bugs was a little more tricky, after a long arduous hunt for interceptor i came across 4 doses and dosed accordingly never seeing them again. as some of you know i am away at school leaving the care of my reef to my dad for who the most part does a wonderful job, i was home for a short bit earlier and noticed some color loss in 2 of my acros. i was curious because i knew everything was perfect so i dipped one of the pieces and found aefw. after this i tore apart about 1/3 of my reef to dip in a mix of fresh and bayer advanced complete insect killer i got after the red bug incident. the first piece i dipped i just threw out because i had 2 frags growing out doing great, the other is a rather large colony of ora red planet. so after about 5 minute dips of the corals and surrounding rocks and then about another hour and a half of trying(but failing) to make everything look back to normal like before i ripped it apart. am i free or do i have to do more dips? i heard of some wrasses being natural biological predators to these aefw, if so which ones are they? also this is the first outbreak i have had since that initial problem months ago and have not gotten any pieces that would have had aefw on them
