Found the two critters on glass this morning by time i got camera they were on rock and shell.They have a white under belly long with what looks like little pink polyps on top of body.

Cool Debby! It looks like a species of Sea Pen!

Sea pen - Wikipedia, the free encyclopedia

Debby · 05-26-2008, 02:53 PM

Is that bad or good and where did they come from?

panmanmatt · 05-26-2008, 02:54 PM

Looks like a coral eating nudibranch to me. Sea pens don't normally move around, unless taken by the current.

Have there been any recent additions of new corals?

That could also be why the one is on that dying gonipora coral.

Dentoid · 05-26-2008, 02:56 PM

I can't be sure what it is, but that is what it looks like. It's probably a hitch hiker that came on some rock. Is any part of it in the sand? If that is what it is, it is not harmful. They are reported to be difficult to feed.

Debby · 05-26-2008, 02:57 PM

yes i added a green star polyp and a giant cup mushroom about 4 days ago.

Dentoid · 05-26-2008, 02:59 PM

Matt, I couldn't really tell by the photo that's why I asked about part of it being in the sand. It looks flat in the photo.

Debby · 05-26-2008, 02:59 PM

no dentoid they are not under the sand.

Dentoid · 05-26-2008, 03:01 PM

Then Matt is closer to the ID. Consider removing!

panmanmatt · 05-26-2008, 03:01 PM

Did you dip or treat the new corals before adding them to the tank?

Scott, I have attempted to keep sea pens before and never had them crawl on the glass. Her description of that is what led me to think nudibranch. I will admit, those pics are a little bit rough for a positive ID.

Debby · 05-26-2008, 03:05 PM

here it is again it keeps moving

panmanmatt · 05-26-2008, 03:07 PM

Definitely a nudibranch. I'd remove them as soon as you can.

Debby · 05-26-2008, 03:10 PM

so what is a nudibranch?

Dentoid · 05-26-2008, 03:13 PM

If it's moving that fast, it is definitely a nudi. I would consider removing it.
