Live rock “zit”

Anyone know what this is - really looks like a zit. I’ve noticed two of them. 90gal tank, about 5 weeks old. 3 fish, no corals. Parameters have been great. First time post so thank you.

It’s hard to tell exactly what you’re referring to. Could you upload a pic with more white light?

Hmm...what should I expect from it? Good or bad?

I agree, it does look like a pineapple sponge. They’re harmless filter-feeders the clean the water
