small moving spots on mushrooms

[arowanaman420]

I recently purchased a nice assorted mushroom rock at the LFS. Several of the polyps have small reddish spots on them about the size of a match head. The other day I noticed they were actually raised bumps on the polyps and not part of the mushroom itself. I was amazed to see them move! They remind me of an amoeba or something similar. Any ideas?

Sounds like red flat worms and they are a bad thing to have in a tank. I would take that rock out asap and get some flat worm exit and place the coral in a bucket of SW with FW exit for 30 min or so. If they moved onto your tank LR you may be in for a battle in the future.
They reproduce so fast its amazing. My friend has a FW infestation and they are so think you cant see the SB. He is going to do battle with them soon. I have them in my Fowlr fuge and they have not taken over too bad, it seems the low light in the fuge is keeping them in check.

Thanks. After doing some research it appears to be waminoa sp. 1.
