Help with identification ?

[AquaJunkie]

I don't think it's a mushroom, it's shaped differently. Need to know what it's is and weather it's good or bad.
Must be strong because its survived through nitrates and seems to be growing.

Kinda hard to picture it at the right angle..

Any ideas?

Could be mushroom, but I am thinking macro algae of some sort. In the last image there looks like another piece above the larger piece off to the left. One way to know for sure is to touch it. Corallimorpharia usually with drawl a little, macro algae will not. Try getting an image at another angel too.

I'd say some type of sponge

I've tried googling all your suggestions and it don't look like any of them.
The only other info I can give is that my regal tang loves to eat them before they have chance to grow lol

Looks like Lobophora to me.

Yeh it kinda does look like lobophora algae
But it's really florescent under blue light and sways quite abit with water flow.

To me that's the giveaway. It's a macroalgae. My tangs will not eat sponges nor mushrooms, but they will decimate any algae.
