Please help! Possible Nudi attack!

Please help. I think these guys are responsible for wiping out one of my Zoo colonies.

Can someone tell me what they are, and if they do eat Zoos, how to get rid of them!!!

Thanks in advance,

Mario

look more like flat worms to me. And if I am right they are the red tipped flat worms that actually eat acropora corals, sure they would munch on other stuff too.

Agreed, flatworms.

Careful when dealing with these guys and research them. The store I work at had developed a case of these recently when working trades with locals.
A 300 gallon system was infected, but only one side of it. The sock filter on the sump was good enough to keep them from spreading to the second tank.
The infected system just happened to be the SPS display system with some hard to replace corals.

We fought them by tearing down that side of the system. We filled a few 45 gallon buckets with fresh water and dipped all the rocks and most of the corals into the fresh water. You see the flat worms falling off instantly. Most of the more common, and hardier coral we would slosh through the fresh water a few times, the more rare stuff we would barely use the fresh water on, sometimes even useing a syringe with fresh water in it to shoot the flat worms off one by one.
We then moved all these corals one by one to the other side of the system. Once all of the rocks and corals were out, we filled the entire tank with fresh water, scrubbed it down with a sponge and scrapper.
The rebuilt that side of the tank. It took three people about 16 hours the first day, and 8 hours the second day to finish this product.
Then on the first business day which was last tuesday I dropped a bottle of flat worm exit into the tank just to be sure.
I think we lost about 3 pieces all frags, and I don't think any of them were rare, mostly Pavona.

I will warn you! read the flat worm exit instructions. And then do something along the lines I was just talking about.
One 10 pound piece of live rock covered i flat worms would turn a 45 gallon bucket of water dark brown in an instant!! These worms killed in your tank will kill everything with them.
They are nasty, and while the method we chose seemed a little bit of an over reaction to me, I quickly saw why it was the best idea.
Never just use flat worm exit, unless you know you just got them and that it won't be a problem

I also hear rumor that if you use flat worm exit and it fails, they will be immune to it after that. I do not know if that is true or not.

Some people suck them out with pipets or turkey basters, once all are taken out of the tank, they dose the tank with FWE ( flat worm exit )... taking the FW's out lessens the chance of nuking a tank from FW die off.

zoaid.com has a list of pest

Those buggers look evil!

try to suck them out with a siphon or turkey baster. then dispose of them quickly. if you see any on your corals, take the coral out if you can and do a freshwater dip. this should knock them off.

Those are Red Planaria, not AEFW. They're quite harmless and are more unsightly than anything. The only real problem they can cause is if they die off in mass they can realease toxins

Thanks for the correction on type. What was the proper ID for AEFWs I thought the red spot on the tail was the give away, but obviously that's not true.
But the previous post still applies, use a procedure to eliminate as many as you can with out flat worm exit before you use flat worm exit.

Normally you won't ever see an AEFW until you dip the coral and see them come off of it and they're fairly transparent overall. Usually the first indication that you have them is that you notice flesh missing from your coral you will almost never seem them associated with anything but they're coral they're consuming.
