White fuzzy things on glass.

Hi there. I have some white fuzzy looking things in the glass of my fowlr tank. There is also a single large white fuzzy thing on my live rock. Anyone able to identify? Thanks in advance.

Pineapple sponges. Typical to see in new setups. I actually consider them a 'life stage' of everyone's tank as they will grow in numbers before fading away to nothing or one or two hiding here and there.

Thanks for the reply. I googled pineapple sponge and that what they appear to be.
