Found this strange soft growth, all on just 1 piece of LR. It was burred in the back so not sure how or when it started. No additional at all in 2-3 years. It has a texture to it. Any ideas?

Thanks

Sponge!! Good thing It may/may not recede with being exposed to light.

It was in the back but on top so it was still exposed to 500 watt of MH. Will try and Google and see if I can find any kind of similar sponges.

Good luck! Very pretty yellow at that and I can see at least 2 siphon tubes

Yellow sponge...good indicator of a healthy system.....
I have it in my sump all over the rock in the final chamber....
The only places sponge is visible in my display is where the Angelfish cant get to it.....

I have had a Bi-Color for years and he never bothers anything

My Regal has always gone after sponges....
It didnt touch any softies or my clams for the first 3 years I had it....
Then one day it snarfed down some brand new Devil's Armor Zoas and began nipping at my clams....
So dont be surprised if your Bi-Color Angel changes its mind and goes after it one day.

Well he's been in my tank for 6-7 years, and it is a mixed reef, with a little/lot of everything. But you never know
