What is this on my Zoanthids?
Woke up this morning and saw this what patch on my zoanthid colony. It's soft -- like a spider egg sack or something. I've never seen this before. It wasn't there yesterday.

Oops. Typo.
Meant to say **White** patch. If there's a way to edit posts here, I can't find it. |

My guess would be a sponge as well, but these things usually don't show up out of the blue like that though. (especially that size) Maybe it got dislodged from a rock and this is where it came to rest.

Certainly didn't come from a rock. I'm using Reef Cleaners rock and it's clean.
It's the strangest damn thing. Aside from the Reef Cleaners rock, which was 100% clean, I've carefully inspected the few pieces of coral that I've added to the tank and this white stuff didn't exist before this morning. It seriously looks like something laid a larval sack overnight. Are there any critters that can do something like that? Snails? Anything? |

It has clearly grown since this morning! Look at those three polyps on the bottom edge. I'm thinking this is not something good...

After reading several other threads on various sites, I believe this was a fungus of some sort. From my reading, sponges grow around the polyps but don't directly damage them. Whatever was on this rock was dissolving the polyps.
I took the rock out of the tank, broke a few pieces off the clean end of it and then trashed the rest of it. Whatever the white stuff was basically turned to a slimy mucus by the vibration of chiseling through the rock. Definitely not a sponge. |
