What is this??

I was just curious why cotton balls are growing in my tank? I have about 20 of them but this is the rock with the most on it. Any input will help thank you!

Should I pull them out of my tank? Because there are about 20 of them they are multiplying like crazy. So they are ok to the system?

They are harmless filter feeders. I have a bunch of them also. No need to do anything.

I agree with the above post. I had quite a few of those little guys after several months, but they're all gone now. It seems like there are several different stages that your tank needs to go through as it becomes established, and that is one of them.
