Fungus/Sponge ?? on Zoa

[whowadat]

Hello,

I came back after a long day out of town to discover a small colony of green zoos had some fungus or sponge growing on it. Any insight to what it is, why its there, and how to get rid of it ??

I would mention that I posted yesterday about the need for moving my torch coral from this same colony which was looking big and beautiful prior to today. Could the torch of stung it leaving behind this whiteness ?? I moved the zoanthids yesterday away from the torch, from mid tank position to an upper area with some zoas others nearby - T5 lighting and I don't see this on the others. This particular group has been in the tank for about a month to 6 weeks with no previous problems. (water parameters are normal and unchanged)

Thanks for your time!

Looks like it might be a sponge. I would try to manually remove all of that stuff with tweezers and see if it grows back. I'd be concerned about that brown 'algae' that is trapping bubbles. Its either cyanobacteria or dinoflagelletes and neither of them are good.

cyanobacteria or dinoflagelletes and neither of them are good. But are treatable luckily
