Flat worms?

I have noticed for some time now that these strange reddish purple blotches/spots keep showing up on my mushrooms. They easily wipe right off and sink to the bottom of the tank. I have not noticed and ill effects caused by these spots, but I'm still curious as to what they are.

Google flatworms, specifically red planaria

I agree with Corailline, it's most likely flatworms if they just wipe off.

 

Here are a couple of pics showing these spots on my hammer coral and my mushrooms. Is everyone still thinking flat worms?

 

If those aren't flatworms then they're some other parasitic creature that you'll want to get rid of.

 

Here is an additional picture I took tonight>>

 

While I do not know the exact type of flatworm, they sure look like flatworms to me still. They may not eat the corals, although I do think those look parasitic, they will prevent or diminish both light and oxygenation to the coral they are covering.. I would start researching flatworm exist and see if that looks like an option. If you decide they are flatworms, of which there are probably thousands of different kinds, either bump this thread or start a new one on treatment, it gets complicated. You just can not treat without removing as many as possible first. When they die that release a toxin as they die that will nuke a tank.

 

Will do thanks.

I will document the process as best I can and relay the results to everyone.
