After my AEFW incident, all new frags get a dip and a close inspection. You only want to go through AEFW once in a lifetime.

The eggs aren't so easy to spot. The coral needs to be air dried a bit, and they can be in some very tight spots; every nook and cranny has to be inspected, this is a very important part of the treatment.

Brad, if you end up with AEFW, unfortunately the only way to eliminate them will be to remove your corals for dipping. It took a long sleepless night before I resolved to do this. Fortunately for me my corals were little more than frags.

You may not have to remove all your corals if you act quickly, they seem to have their favorite pieces, my tri-color was especially tasty apparently. If there is no recession at the base it may be OK to leave them attached... and see how it goes.

Rob, the corals just don't come out without removing most of the rock. Some are encrusted to the rock over a 6" area. If it gets to that point, I'm done. There is no way I can remove all acropora tissue for multiple dips and place them back in tank.
This is still only a small possibility though, so we'll see what the year brings.

Just keep a close eye on them and be resolved to act quickly if need be. You may not have to remove all your corals if you can deal with their "favorite" before they spread. All infestations seemed to be characterized by base recession.

Yes, good point. If you catch it early enough there may only be a few corals affected since AEFW, like red bugs, always have favourite corals to munch on. Once you figure out their favourites you can continue to monitor those favourites in the future.

Awwww guys that so sucks! Just another reason I hate those damn acros.
I hope Brad you caught that frag in time.. And Wayne hopefully you can get them stopped!

those will eat red planaria. Not sure if they eat AEFW

I have been doing some legwork on sourcing:
BAYER ADVANCED COMPLETE BRAND INSECT KILLER
in Canada. The active ingredients are:
1) Imidacloprid and
2) beta-Cyfluthrin.

1) Imidacloprid is the active ingredient found in many topical flea medications that are available in Canada such as Advantage II as well as crop pest control agents also available in Canada.

2) beta-Cyfluthrin is another common pest control agent and can be found with shipping available to Canada here. The MSDS for the linked product is here.

Were somebody suitably motivated, the information and sources above should enable you to recreate the Bayer product used successfully in the link Reefer Rob posted up about a dozen posts back. If you guys would like me to try to put it together I would be happy to put some more legwork in and get it together.

Failing that, I am happy to donate frags to either of you with no limits to quantity should the need arise.

I think at this point my only concern is future stock, so I'll be taking frags of everything, making sure they're clean and finding them a home. Other than that, I'll watch and wait. Hopefully it doesn't become a problem.

As for Wayne, he's tearing the tank down for a rebuild anyway, so that should allow him to more easily sort this out. Bet he's glad now that he didn't mount his corals like I told him to :)

Thanks for the post Dan!

Dan, this would be an interesting project and could make you high in demand.
I am working on a rebuild so that may not be of a huge concern however my concern is will these flatworms lay eggs only on dead sps corals or will they lay eggs on rocks as well? If so is there another way to rid of them besides dipping the rocks or using insecticides?
