Can anyone tell me what this is and if it is reef safe?

When you find out let me know. This appears to be the same thing I have growing. As it progresses, it takes on a tentacled / tendrilled appearance branching to other rocks.

Anyone else got a clue?

Well, this is great. If the ionization-rate is constant for all ectoplasmic entities, we can really bust some heads... in a spiritual sense of course.

Any idea what kind of sponge, it extends itself away from the rock and waves in the current, which made me think it was aiptasia.

My guess would be sponge as well. It doesn't get any light, does it?

It didnt get any light before, but now since I have moved the rocks around a bit it does get light.

No, not that I'm aware of. Most sponge grows in our tanks and seem to be limited in how large they get. Perhaps some fish will take a liking to it and reduce its mass.

The only risk to your reef is if/when you pull out the live rock for some reason and expose it to air. The sponge immediately starts to die off and when you put it back in the tank, it can cause an ammonia spike. So try to remember that if you reset your tank, and scrape off all the sponge you see - or put all the LR in a vat of saltwater to keep it submerged.

I think it is a sponge too. If it is a sponge then it is in the Class Demospongiae but there are like 20 orders and ~5k species in that taxon. I'm sure its harmless to you and your organisms.
