Critter ID help please

[ReeferNick13]

Noticed this little critter early this morning before the lights turned on. It almost looked like a tiny cotton ball with two antennas. Does anyone know what it is? Do I need to try to remove it or is it ok to be in the tank? Thanks!

Google spionid worm, see if it matches up

So I just got in there and removed the frag and noticed them all over the plug, can anyone tell what they are?

More sponge and Spirorbid worms.

Pineapple sponge.

Harmless filter feeders. They will usually grow in darker / shaded areas.

They are good CUC
