flatworm question

[ReefingFreak]

Now, I know this is supposedly the kind of flatworm that eats copepods, but, is it a possibility that it is eating zoas? For some reason my zoas haven't been open for a few days and I have seen a few of these on them. Is it possible that they are killing them? :confused:

Looks like a common flatworm... not the 'red dot' photosynthetic kind that can cover and kill off corals. A lot of people have them.

You can live with them and keep that under control by watching tank nutrient levels... you can pick up a fish that -may- eat them.. such as a 6-line wrasse (read up on their pro's and con's).. or treat the tank with flatworm exit.

There are a number of threads on treating a tank with flatworm exit. Just be cautious. If you see a bunch on the glass, there are certainly a lot more on your rocks that you don't see. When they die, they are toxic to the tank. So a treatment must be done properly to siphon dead/living ones out, treating the tank, and doing an adequate water change and running carbon to remove toxins after treatment.

Flatworm exit never takes all of them out. I've done multiple high dose treatments to try and take out some zoa eating nudis and somehow in two days I'll see a lone flatworm that made it. I'm leaning more toward the wrasse idea.

I allowed the salinity in my tank to get real high and it seemed to kill all of them.

Hmm, that is what I am afraid of....

Hey, thanks. I really don't want to treat my tank with anything. I am more leaning towards that wrasse. Will any other wrasse possibly eat these? I really don't like the sixline, I don't like all the stories I hear of them harassing other fish. I usually only see about 10 or so on the glass. I know there are a lot more that I can't see.

I am also leaning towards the wrasse...

Sounds interesting. How high did you let it get? I keep it at 34 ppt right now as it is.
