No bite marks or eggs that I can see through the front pane. Checking mostly the underside of the stressed colony but also the top.

I would almost guess its aefw, besides that there are asterina stars that will eat acros and red bugs. I would take out a colony out that's dying and dip it, if that's not possible than cut a good size frag off and dip that. In the mean time, purchase another wrasse and start blowing your acros with a turkey baster once a day. Its not gonna eliminate your problem but its should control it.

Other than that, the only thing could kill your acros from top down is Alk swings.

Good luck, fingers crossed its not aefw, but in case it is there are methods to get rid of them, don;t lose hope.

you will never be able to see unless you use a high power flash light at night and really really look close at the bottom for bit marks. Valida is a favorite so check those first.

Rich ... Thanks. My other 3 valida are in close proximity and are doing real good and thriving. I mean REAL good in every way (polyps, color and growth).

Just dipped a large 4+ inch multi-branched frag of the affected turaki. Nothing unusual after 10 minutes.

Been no alk swings so I am still looking for suggestions and still puzzled.

I love wrasses so I'll buy another melanarus wrasse on the weekend when I am at J&L. If they have 3-5 juv yellow coris wrasses I'll pick them up too for pest control. I've always wanted a herem so this is a good excuse.

Time to cross the fingers and hopefully Kien can throw a prayer into the prayer reactor for me!

Could you post some pics of affected colonies?

I wish. Tried many times but I've never figured out how to post pics on Canreef.

I permanently removed and dipped 2 super stressed colonies and no flatworms. Turaki is too big to remove but cuttings have had no flatworms when dipped today

Easy. Open a photobucket account and post the links.

This guys says he has an AEFW treatment if it is that. Pretty interesting thread.

Dipped frags of the affected corals and didn't see any flatworms so not gonna panic quite yet.

Gonna read that thread thou as I'm a bit out of the loop on in tank AEFW treatments.
