Please ID these 2 gray mushroom shaped objects in center of pic, just left of the Zoas. It's a slow grower, but not very pleasing to the eye.
Friend or foe? Let it be, or eliminate?
Got Sponge??? When is too many?

They look like some sort of sponge IMO. How do they feel to the touch?

Ball sponges, harmless.

I think he might be referring to those pinkish/tan spots to the very left of the zoanthid polyp, not the white balls all over the rocks.

 

[meir]

I think he is referring to the thing directly to the left of the lower polyp

Well I can't make it out enough for a definitive. Out on a limb I would say Corallimorph vs Paly or Zoanthid, but that is just a guess.
With regard to sponges it's my experience that populations wax and wane as a tank ages. With the exception of liver sponges I never had a sponge type get out hand or invasive.

Thanks for the reply, and yes, I did mean the gray blotches. They are very slow growers. Very hard to the touch. No extensions of any type. Seems to be encrusting. These were half the size a year ago.
It seems Coraline algae is encrusting to the left side.
