Hello,
I noticed these months ago on power heads in my tank. Since i removed the power heads i have not seen them in the tank it's self. Yesterday i noticed them again in the filter.

My tank is a 100 gal saltwater FOWLR. I have 40lbs of live rock, reef octopus HOB skimmer and a Rena canister filter. Specific Gravity is 1.024, PH is 8.1, Nitrates, Nitrites and Ammonia are 0.

Just a bunch of sponges, they are harmless and filter the water. Looks like a few pineapple sponges.

Stomatella? Google that and see if it looks right?

These things dont seem to move, the Stomatella seem to move based on a Google search.. Close though, they look similar.

+1 for Pineapple sponges. Have a TON of them in my sump.

Yes, if they don't move, I would also guess pineapple sponges.
