Yep that is sponge. Harmless filter feeder. You can always use a soft toothbrush to get it off.

Edit to add: it can grow over coral which will kill it so just make sure it does t get to close.

Hmmm I don't like that one bit, especially because its hard to see the underside of that coral. Would dipping the coral kill it?

I've never dipped a coral just for sponge. I just take a soft tooth brush and brush it away. It comes off very easily so I don't see a need to dip.

I was able to get a lot of it off but not all. It had spider web like consistency to it. A bit lighter than slime algae. Alot got released into the water column, hope thats ok!

Well, this sponge has gotten out of control and my candy has started to bleach. I am not 100% confident the sponge is killing the candy, but I don't see what else could be doing it. The heads are bleaching from the inside out, which is where the highest concentration of sponge is. The heads start with bleach streaks on them which align with how the sponge protrudes from the coral (like tentacles. You cant really see it in the picture).

I dipped the candy and scraped off as much sponge as I could but there is still tons of sponge in the center that I will never be able to touch without fagging the coral.

Does anyone have any advice on how to kill this sponge without fragging the coral? Maybe a fresh water dip? Or an animal that would eat it?
