Flatworms... ewwww....

[justinl]

if you do end up with flatworm exit, you need to dose about 5 times the dosage on the bottle, then run carbon immediately afterwards to counter the toxins the flatworms will give off as the die. if you do the recommended dosage, you wont kill a single flatworm.

my melanarus wrasse seems to keep them at bay

[Robw]

I had flat worms for about three years. Did multiple doses of FWE over the course of three years. I even pulled all the rock and soaked it in SW with FWE and blew all over the rock with a power head and they came back. When I moved from Yellowknife to Calgary I had the rock in tubs of saltwater with heaters and powerheads running off an inverter with a triple dose of FWE in the water in the back of my truck for two days. They still came back! I finally gave up with the FWE, it did kill them but not every last one. I started to do regular water changes and sucked up as many as I could. I did buy a yellow wrasse to see if it would eat them. I never saw him eat any but they eventually did go away, kind of just died off. The yellow wrasse sleeps in the sand bed. Freaked me out one morning when I saw just its head sticking out of the sand bed. I thought something ate it and left the head laying there. Until I noticed the gill covers moving. Neat watching it circle it sleeping spot in the sand then burrowing in. Kind of like a dog lying down to sleep. Now I am off topic and will shut up.

That is certainly not my experience. Recommended dosage certainly killed a lot of them in my case. I was impressed that it really seems very targeted. I saw one Eunicid worm in distress, and I'm a bit worried about some starfish...other than that, there seems to be no side effects to the treatment.

I'm waiting another week to see if I can see any alive. Robw's experience is very concerning. I don't want to transfer any into the new tank.

The idea is to preserve life on/in the rocks while eliminating the flatworms. Aggressive treatment of the live rock is not an option.

The good thing is that they are finally gone. (knock on wood)

Well, I'm going to tell my wife that I NEED a wrasse - first. Tehehe. FEW seems to get mixed reviews. If I can find it, I'll give it a go - if not, I'll stick to manual removal.

The tank is a 55 gal and reasonably stocked.

Thanks again for all your suggestions!
