Anyone know what this is?

Hey everyone. So I’ve had this “sponge” looking thing growing like crazy the last couple months. Just want clarification if it is in fact a “good” sponge and not something I should be worried about. Tank has been running for 11 months. Started with live rock.

unless they start to smother corals you should be fine, i can’t chime in on the specific name or anything but i’ve had these come and go for a couple years with no issue across multiple tanks

Should easily peel off things it attaches to, snip it back and toss in the sump

Thank you to you both. It was climbing up a gold hammer and I just took it out and pealed it right off. It does look like it’ll take over so that’s what got me worried
