White Mold on my LR

[cfedarko]

Not sure if it is totally clear in the pictures or not, but, it truly looks like a white version of the feathery like mold you would find on month old leftovers in the fridge, not like the hard-poured-on-paint sort of idea that you get from sponges...

Help please - need to know if this is detrimental or not. I have two large LR's, a porcupine puffer, snowflake eel, and maroon clown - no cleaners cause the puffer ate them all...

Thanks!

Tagging along. I have the exact same stuff on my Fiji rock.

I have something similar on a few of my rocks. On one particular rock it seems to have veins. I was assuming it was some kind of sponge. tagging for answer.
