Giant Mushroom Parasite ID?

[SoonerFan732]

In the pictures below there is some sort of creature living on my Giant Mushroom. They are mobile as I can watch them move around on the mushroom. They are flat and round as you can see in the pictures. The mushroom has been shrinking for a couple of weeks and now I am starting to see holes in it. What are these and how can I get rid of them?

Thanks!

Look like flatworms to me. But it is kinda hard to tell from the pics.

flatworms you had better get them off that mushroom fast, although i would say to freshwater dip the whole mushroom and the flatworms will fall right off...hope this helps!

Is it really safe to do a freshwater dip on mushrooms and how would it be done?

Thanks! How should I go about a freshwater dip?

make sure the temp and ph match that of your tanks, and just dip and swish for maybe 30 seconds, then look at the shroom, remove the visible ones that didn't fall off, and do again. You need to get some flatworm exit for your tank though, or you'll get infested and lose lots of sstuff.

They look like Nudibranchs to me, many of which are harmful predators disguised to look like the coral they prey upon, much like the ones in your picture. I'd try the freshwater dip. It works with much such pests. Good luck!

they look a little lighter in color than most flatworms I've seen. newborn Nudibranchs is kinda the direction I was thinking...but, I was thinking newborn Cuttlefish??? I know that sounds wierd but, I've seen some pics somewhere lately...found it...

these things mimic the color of their surroundings very well. This is probably a pretty far fetched ID, but just thought I'd point out another possibility besides flatworm, which is far more likely...
Have you added any new rocks or anything lately?
