Please ID hitchhikers on live rock!

[mayland]

Hello, setting up a new tank and we got some live rock from a local reefer who said it is aiptasia free. Looking for IDs on the brownish circular things (left hand side). One of them sticks up a few millimeters (side view pics also) but doesn’t seem to have the tentacles an aiptasia would.
Also think we have some bristle stars (are these okay? There are 3-4). Thank you so much!

I see a couple of filter feeding tunicates and macroalgae which may be Ulva and a serpent star ( a keeper for me)

Last one is a brittle star

Is the tube like thing hard?

Is the tube like thing hard?

Are you speaking of the white thing in the last picture?

Is the tube like thing hard?

Same question... looks like vermetids to me

 

[EeyoreIsMySpiritAnimal]

And brittle stars are fine (as are bristleworms )

 

[mayland]

Yes the brown tube thing is hard. Is that bad?

No, they should be fine as above vermatids

 

[Michael71]

No, they should be fine as above vermatids

if you see them shoot out a mucus like net or string during tank feeding, that is a confirmation of the vermetid ID. they are a type of stationary snail.. the net can irritate corals but never had issues with them bothering coral in my tank. If they become too populous i have heard bumblebee snails will eat them

Thank you! Googling makes these sound very bad! Do they have any merits? There is a snail that I would describe as bumblebee-like on the rock also (pic attached). Is this a bumblebee snail? Thank you so much.

Will the ulva algae take over? That is on a smaller rock - would we be best to move that to the sump?

 

[Spare time]

Probably a vermatid? If so, crush it with plyers. They can become problematic

Get a turkey baster and blow those rocks off every day, there is a lot of particulate on them.

Yes that looks like a bumble bee snail

Slow growing and harmless

 

[mayland]

Also found this little snail (maybe 1/2” across). Is this a good or bad guy? Thank you all so much for your help.

 

[Michael71]

Maybe a margarite snail, if it is, good snail, eat algae

That looks like a sundial to me. If so, not good at all.

I checked those too, but the banding isnt as prominant as a sundial...continuing to follow
