Weird curly black things growing

[MAB Reef]

Hi, anyone know what this is? There are a few smaller ones growing on frag plus too. This was the easiest to get a pic of.

Sorry, but only can guess from the blurly photo, so Can be sponge, mushroom, tunicate (never saw that dark), or sort of coral.
Try to take another angle photo Please, or if you can take it out of the water for photo, and/or another photo when it's under very shallow water.

Looks like a vermetid worm, I would kill it.

can be, but completely not sure about from the description and the photo.
Can you describe it please, is it hard to touching, do it have pipes on it or something else ?

Going to say black tunicate.

Newbie help coral ID please?

I am not a newbie so this is meant to be educational for newer viewers. I use a camera on my tanks, this is with my phone, iphone 7, there are a lot of early responses on posts that read "can we have a pic under whites please", this is also under the stock leds of a fluval 52 / 13.5. hold your...

It is hard to the touch. Let me try and take them out and get a better pic

Hopefully these come out better. It is hard to the touch. It has a ridge like surface on it.

Def not a tunicate. Vermetid.

Long nose pliers. Break it off and chuck.

Just want to make sure. There are a bunch of tiny white curls growing all over the frag plugs too. Are these vermitid also?

Those are spirobid worms good guys

No, spirorbid snails.can scrape if they obstruct your view but harmless.

Definitely vermetid both the black, and the white ones in the last pic you posted. I have both of those in my tank as well, I'm not sure how feasible it is to get rid of them entirely but I just put a dab of superglue on any that are on or near my coral frags and then they can't come out of their little spiral shell. There is a snail/worm inside the spiral shell that typically lets out mucousy strings to catch phytoplankton, and said "strings" can bother your corals but other than that they aren't really harmful.

 

[Strangewaterchange]

Those are not spirorbid snails. They are smaller vermetids. Spirorbids are much smaller and will grow on glass and rock in low flow areas but are flat and the end of their shell doesn't come outward/upward like the vermetids do, as you can see in the last pic you posted there are several that are clearly pointing up away from the spiral body at the end.

Thanks all! Really appreciate the help. I'm learning a lot from this forum.

They may be 2 different types of vermetids, but 10 billion percent both vermetids

Sticking with spirorbids.

Sticking with spirorbids.

I have spirorbids and I have those white vermetids as well as the larger black ones in this post. Stick with them all you like but to the poster so you are not mislead, they absolutely are vermetid snails. No disrespect but I know this for a fact.
