Not sure what this is? Sponge?

Just saw this in my tank the other day and wasn’t sure if it is a sponge or what it is? Any info would be appreciated

Hi, it looks like a sponge to me, unless you’re as messy with glue as I am.

Hi, In my tank chances are a blob of glue, I’m messy attaching corals, but in yours it looks more like a sponge

I’ve had the tank for like 3 and a half years and don’t have any glue there. Haha trust me my glue spots aren’t the best either so I feel you. But I’m thinking a sponge too. Which I haven’t introduced anything new for a while now so not sure where it came from.

Also when I first saw it it was much smaller than it is now

Yeah, It’s amazing how things just show up out of nowhere.
