Is this a sponge or algae?

[LondonReefer]

Hi all,

Noticed this thin strand growing on my glass. It's just over half an inch now, but that's probably only taken a few days to grow. Can easily pull it out but thought I'd get it identified.

Thanks for any help

I've not had this before but looks like a sponge to me.

Cool thanks, I'll leave it for now unless anyone else has an idea what it is

Could be the very start of one. Will post here if it grows into anything cool
