Can anyone please help ID this, this is the best picture I can get but it is also around the base of my Zoa, it can only be seen then when the shrimp or something crawls over the Zoa and the heads go in.

Parameters are all normal.

Thanks

Hi,

Can anyone ID this? I know not great pictures but it is around the bases on the Zoa and random points in the tank.
All parameters are normal.
Thanks

Looks like a sponge to me.

Is that likely to be problematic for anything in the tank?
Should they be removed? If so how?

I think it would only be a problem if it grows in inconvenient locations that make you and other things, you deem more important, unhappy
