Hi I am an experienced saltwater aquarist, but this is my first sponge.
I have a finger sponge bright orange, and he is in a high flow area of my tank.

Yesterday i noticed that he has a sponge growth uniformly over his entire surface of about 1/32. but this is pale compared to the orange color underneath the new pale uniform color. At first i thought he was covered in some kind of pale slime, which is unuasual in my tank, it is basically flawless. I touched the sponge to make sure, and found it was actually the sponge, Now I'm not sure is he growing or dying?

The only thing I can suspect is that my skimmmer has put bubbles into the water not a lot, but some, do you think these could be destroying my sponge? Although there seems to be no openings in which bubbles get into the sponge. And I know the bubbles didn't touch every part of my sponge, and they just seem to float by him not actually sticking to him. So it leads me to believe that the bubbles have not harmed him.

Or is my tank so healthy that the sponge is growing, and the orange color deepens after growth?

Any comments well appreciated, thankyou.

Picture of my sponge is attached, it's the one with my clownfish in the picture, is my sponge. the other file is just an example. Mine are the clown- Jeb and Bob the Sponge. If you look closely you can see the thin layer of pale sponge covering the orange on bob, but it is sponge and not slime, I'm trying to figure out if this is normal. It covers Bob the sponge uniformly and completely. it actually looks like 1/32 inch of sponge growth. Is that what it is?
