Pineapple sponges or barnacles??

My brothers told me they're barnacles but they look like pineapple sponges to me

I'd have to vote for sponges.

Thanks!! Yeah there's alot not sure if I should leave em be or take some of them out

 

[Flreefer]

I would leave them, they can only be seen as beneficial, and they generally don't get very big.

Cool, that's what I've done so I'll keep doing just that.
