    What is this orange ish worm with strings coming out of it?

    I see these stringy things coming out of the sand all the time. I believe the worm stays under the sand and puts the strings out. I saw it on the glass and tried to take some pictures. Let me know if you can identify this. Thanks

    Hi- I am a new hobbyist and am just cycling my first reef tank! I went to my LFS to purchase my live rock, and noticed some interesting hitchhikers.

    Please help ID these cowboys riding my snail

    Not sure if they are feather dusters or aiptasia but fairly confident it’s a worm. I am new so looking for any clarification before I put into my display. Thanks. First post. Lurker for long. Finally starting to get hands in reefing.

    Possible Hitchhiker?

    Hi Guys, I added my first coral to my tank on Monday, a single Rasta Zoa polyp. I did a coral dip using Coral RX Pro and Seachem Reef Dip. Over the last couple of days I’ve noticed something that appears to be growing out from the base of the polyp. Any ideas what this can be?

    Coral Hitchhiker ID?

    Hello Reefers! Quite interested in an identification of this clear lil guy. Almost reminded me of a mantis shrimp, because of the way it was walking, but not sure. Possibly a Squillidae? Has anyone found anything similar? Thanks!

    Mojano? Aiptasia? Can anyone help ID?

    Just noticed this on a frag that's been in the tank for about a month. I haven't seen them anywhere else in the tank so I guess it came on the frag, but just now noticing it. Can anyone help ID what this is on the base of this hammer?

    What are these tiny, white crawling bugs?

    What is this hitchhiker ID

    Hey guys, just noticed this thing, and wondering what it is... Was thinking aptasia but not too familiar with it as I've been lucky enough to never have an outbreak. There's also a few pepermint so thought they would have found it if it were. Let me know what you think. Thanks!

    Zoa hitchhiker?
