Is this aefw?

Hello everyone

Just was checking out my tank this morning with a flash light and saw small circular marks on one my newer acros. I can't believe it happened since I dip everything in Bayer.

Sure looks like it

Looks like "bite" marks to me too unfortunately.

Yes..

mirkus · 11/14/2017, 02:14 PM

It even looks like some FW are visible in picture.

I’m afraid so..
I had a real battle some years ago.

Looks like bite marks at the top and the underside. Unfortunately just dipping in Bayer isn't going to prevent pests that lay eggs nor will any dip help for that. Not even clipping the frag down to healthy skin and dipping and remounting it. A lot of people are hopeful that just cleaning new acropora will keep aefw out of their tanks but when we add a lot of stuff we start to get lazy at inspecting pieces and eggs slip by eventually. The best method for keeping them out if you don't have a we tank is to visit a person who has them and see them in person. If you don't know what your looking for it's hard to catch them. Even if you do know what your looking for they will eventually slip by if your actively collecting pieces.

I have seen more aefw come from other reefers frags and vendors corals than I have seen come in on freshly collected wild or maricultured pieces. Buying from "trusted" members or popular vendors gives a confidence that the corals are clean, which is a false assumption and where many people pick up these pests.

If anyone finds aefw there is no reason to act fast and freak out. These pests won't devour a coral in a few days. Keeping your corals healthy is key to keeping numbers down. Some people never even know they have them. And a lot of reefers have them and have amazing tanks that make tank of the month.

Dipping all acros and putting them back in the display tank is the best way to get rid of them in a tank where corals are easily pulled out. This is why I like to always keep colonies on their own movable rock.

bummer man!

That branch on the upper portion of the photo sure looks like AEFW bitemarks. But...AEFW are not as bad as I once used to think. I find them easy to deal with. Search up username "Dowtish". Chris made a thread some years ago on how to deal with AEFW. I followed Chris's method and cleared my tank containing 50 or more SPS pieces.

TheDeepEnd · 11/26/2017, 11:30 PM

Yep, aefw. I've dealt with them in the past by chopping all dead coral and doing weekly Bayer dips for about a month.

Yep those are aefw bites for sure. Interceptor or Ivermectin time, go to a vet and explain to them the situation. I went to an exotic animal vet and got very luck at the interest they had on treating and IDing the flatworms. Bayer works pretty well but in the past I have seem some reports on it not being effective on most flatworms.
