Stuff on rock

[darrenahenson]

Just noticed this on my live rock. I have no idea what it is. Any ideas????

Looks like a ball sponge to me but I'm on my phone so it's hard to see

Good or bad?

Ok the big fuzzy thing is a ball sponge

The little white "Root" looking things are Forams.

Or Byrozoan

Or a sponge

Small white tubes are Spirorbid worms

Or Tube worm / feather dusters

They are all good, they all filter feed and will help to reduce the nutrients in your water.
