No. 2 looks like mini feather dusters and No. 3 you are talking about the yellow stuff beside the mushroom yes I think it is a sponge.

I agree with melosu.

1 is red valonia, aka: red bubble algae
2 look like serupulid worms
3 is a sponge.

is the red valonia algae good or bad?

thx

Not neccesarily bad, not neccesarily good. It can spread rather quickly under the right conditions so most people like the pick it out. Try and be careful though, to not bust the bubbles. It can spread spores around the tank that will make it spread quicker.

I have a group of green bubble algae in my tank that won't go away, so I try and keep it trimmed monthly to keep it to a minimum.
