Id super weird thing in my sump

[Gabbone]

Hi guys,

First thing I see these weird creatures attached on the glass of my sump.
I do not have these in my DT. Just a couple of them hanging in the sump.

I took one and try to make a good pic.

I touch it with my finger and it's soft and doesn't move. Maybe a filter feeder?


Thanks all!!

Looks like a pineapple sponge

Thanks! Yes, it's a pineapple sponge. Just checked. All good!

Usually they go away on there own, harmless filter feeders and common in new tanks.
