This has been in our tank for a few months. It definitely moves around the rock but has not really grown in size in any significant way. Any help identifying would be appreciated.

This is a rose bulb anemone.

That is what we thought...thanks! Unfortunately during cleaning we see this all over our lines. Was definitely not there a few days ago...Any thoughts?

I think those are pineapple sponges. Assuming they are soft?

Pineapple sponges! Harmless filter feeders that thrive in high nutrient tanks.
