Flatworms on mushrooms?

[jdjeff58]

I just noticed these flatworms last night on my mushrooms. They appear to be isolated to this rock with the mushrooms. I posted in another forum but can't really seem to get a positive ID. I'm getting a little panicky and would like to know if these are going to create problems. Should I get this rock out of the tank?

I would remove the rock and do a dip or get a six-line wrasse to eat them.

Try a flatworm exit dip on the whole rock and see what it does to them. Very good picture.

If you try Flatworm Exit make sure you follow manufacture instructions regarding water change/carbon. Have a friend with a huge Flatworm problem lose almost his whole tank (at least a 4year old 90 gal) by skipping the carbon and doing a larger water change.

Take the rock with the flatworms and put it in a bucket and put lots of flatworm exit. Those look to be coral eating flatworms...if they are, I've heard that some are resistant to flatworm exit.

If FW exit does not work, put the rock with mushrooms in ro/di water and swish it around, etc. Hopefully that will kill it. If not, then put some lugols iodine in some water and that should get rid of them.

I dislike flatworms except the white ones because those come and go and never get to huge proportions like the browns ones and the white ones don't hurt anything.

I have had the small reddish brown ones in my biocube and they seem to wax and wane but have not seen any in a couple of months .It was never that crazy but i could probable count 20 or so on my glass and sand . Are the that big of a concern?
