I don't know if it's sponges, it's more flat like and white. Not transparent white like most sponges but powder white.

Anyone else with opinions??

From your picture I'd have to agree with Gary it does look like a sponge. I have them too and when they start growing they don't have a lot of height. Touch it is should be a bit springy. If it is then it is a sponge. Not sure of the specie but if it is the same as I have it grows throughout my rockwork in shaded conditions.

Unfortunately my tank is 42" high and I cannot reach it unless I use an extension grabber to get the rock out to touch it but I don't want to do that since my female Crosshatch sleeps under this rock formation.

If yours is a sponge, does any of your fish eat the stuff? I have a pair of Blueline angels going into this tank next week, maybe they will eat it if it's a sponge.

Looks like that white sponge that starts out kinda spider webby.
Sponge is a good thing, leave it.

To my feeble eyes, from the picture it seems like it is sponge. Which, if true, is always a good thing as others above have stated.

a better picture would definitely help.

are there a bunch of holes in the body?

whatever it is is on top of the rock in the light which would argue against a sponge. what type of lighting do you have right over it?

Can't tell from your pics but does it look like the one in this pic--on the right of the BL? If it's sponge one should be able to see pores on it right?

Nope, it does not look like that, it almost look like the rock is turning white.
