This thing is slowly growing in my sump. It’s 3/4” or maybe 2.5cm across. Thanks for any insight folks may have!

Hard to tell by pic, but might be a sponge.

I'm pretty sure it's a sponge. Nice find!

Sponge, all over my tank, can make some interesting shapes, I take it as a good sign for water quality..

+1 sponge. Have some just like that. Harmless filter feeders.

Thanks all! My guess would have been sponge as well. I’m psyched to have another type of sponge then. Always had pineapple sponges, but this is a new one, and she/he/they/it are most welcome.
