Anyone know what this Blueish sponge is?

I can’t seem to figure out what it is? It’s multiplying into little blobs on my LR. Just want to make sure it’s reef safe.

Looks like a common (Blue) sponge, it’s reef safe as long as it doesn’t encroach on corals.

agree with above, very nice sponge but can soon take over as it spreads so keep an eye on it, although it doesn't like bright light, much preferring shady areas.

That’s funny you say that, it’s on my live rock closest to the LED. Should I move the rock Farther away?

It's gonna grow where it wants to. If it's already there, it wants to be there. Harmless, beneficial filter feeder. I see sponge growth as a sign of a healthy tank.

All of my sponge grow on the bottom side of live rock out of direct light. Just keep an eye on it. Cool looking though!
