Alberto,
Sorry to hear of your recent infestation.... I hate those things....
I found several on an A.albrohensis frag I received from a friend. He warned about having seen some in his tanks while I still had my frag in QT. I looked carefully and found one. I was able to remove it by blowing it off with a turkey baster, and I dumped it down the drain. I put interceptor and flatworm exit into the tank in order to kill any other unwanted pests and moved on from there.
A few months later, I noticed one of the two albrohensis frags on the rock was closed up with no polyp extension. The coral looked really bad. However, the larger of the two frags, (the one I originally saw the flatworm on) was fine. After a couple of days of close observation, I saw a slightly off colored section of the coral. I pulled the entire thing our and placed it into a small glass of tank water. I used the turky baster again and was horrified to see a couple of acro eating flatworms come blowing off in the current. I moved the acro into a darker tupperware container with tank water and began to blast it with the turkey baster. Each squirt knocked 3-5 more acro eating flatworms off the the smaller frag. I was finally able to remove approximately 25 or so flatworms from this one frag. I carefully removed all of the flatworms and placed in the same glass the coral had been in originally.
I dosed Flatworm Exit in order to see if these were affected by it. After 10 minutes with no effect, I doubled the dose. After another 10 minutes, I again doubled the dose, (4 x reccomended dose). After 30 minutes of them sitting in the FE treated glass, I saw no visible effect on these flatworms by FE.
I added a few drops of Iodine to the glass with the flatworms, just enough to make the water a light tea color. The effect on the flatworms was immediate. They were all killed in less than a minute and began to dissolve within 5 minutes. I placed the albrohensis frags (same rock), into a fresh glass with more tank water and added a few drops of Iodine to the water. The corals closed up and looked pissed, a few pods and micro brittle stars died, but saw no flatworms. Again the dosage was just enough to make the water a light tea color...
I left the corals in the iodine treated water for 10 minutes and then placed them back in the tank.
The larger of the two had its polyps out within 30 minutes, but the smaller one (the one with the heavy infestation) didnt open back up again until the next day.
Both corals appear to be doing fine so far...growth continues to be good and the smaller albrohensis frag is doing much better.
Whats interesting to me is the fact the flatworms never moved over to the larger frag from the smaller.
I know my treatment was far from scientific...did the iodine work by itself, or was a synergistic effect of FE and the iodine? I didnt exactly measure the dosage of either the iodine or FE...so who's to say what really nuked the acro eating flatworms...
I'm just trying to be objective about what I saw and did.
I have more pics besides these if you'd like to see them as well....
The quality isnt that great, you definately wont be able to get an ID of these worms based on my photos....
First pic is of the two frags in QT. The frag on the left is the largest of the two. The white spot you see on the frag is the one flatworm I saw while the coral was in QT. (Its in about the lower 3rd of the coral, in between the two small nubs beginning to branch off)
This is the same coral after treatment.....as you can see the distance between the two frags is pretty small.
I dont want to hijack Alberto's thread, so I'll hold off on posting the other photos here...
