It is directly in the center of photo not sure how well it will show. thin as a hair, alternating stalk is brown and white. the "club" on the end is like a thin dandelion seed head spikes with small white blunt ends. hope the photo is clear cant really tell with photo bucket. If not I will set up macro tomorrow evening.

Guss · 11/06/2013, 08:01 PM

Sugar.... Here is a video for you to see, hopefully better than the pictures.

Guss · 11/07/2013, 04:54 PM

This should be a little clearer

CarlosPulga · 11/08/2013, 03:00 PM

I had these tube worms(?) for a while, I like them, but now I'm curious to what they are called. Thanks. =)

this is not a pencil urchin but looks like it is most likely a reef urchin Echinometra viridis the white rings around the base of the spines is a good way to tell the difference

JiveWalker · 11/08/2013, 06:56 PM

Not sure how I've missed these in the past, but there are quite a few of them. Are they limpets? Are they good or bad?

pagojoe · 11/08/2013, 07:45 PM

Yes, the more primitive of the so-called limpets, it's a keyhole limpet. Most of them are harmless.

Ahhh I looked it up and looked a the tank. Looks to be the same one.

Thanks!

hogfanreefer · 11/10/2013, 03:55 PM

Good crab, bad crab? I'm thinking bad judging by the pointed pincher.

Sugar Magnolia · 11/11/2013, 01:30 PM

Some kind of xanthid. Toss it in the sump.

Reef Man Dan · 11/12/2013, 12:20 PM

Hey all, while doing some equipment mods in my sump I came across a ton of these things growing on the baffles. There are probably fifty growing, and some, like as you can see from this pic look a little different. Are they some kind of larvae? or something nasty that needs to go?

Thanks!

Sugar Magnolia · 11/12/2013, 12:28 PM

It's a harmless scypha sponge. Also called pineapple sponges.

Reef Man Dan · 11/12/2013, 12:38 PM

That is definitely what it is. What appears to be cilia really through me off. Thanks!

thrawn150RT · 11/14/2013, 02:59 PM

I have these little starts all over my tank no idea what they are

SantaMonica · 11/14/2013, 10:19 PM

Asterinas

Reefer54 · 11/15/2013, 08:09 PM

this has been growing on my snails shell for the last month or so.....never seen one like it. It seems to have sweeper tentacles or the like that come out of the center top...they look unclear in the picture and video, but they are there.

What it is (question mark) (my kids broke my question mark button, and my "sideways N" button too)

Reefer54 · 11/15/2013, 08:10 PM

maybe better focus

Rob in Puyallup · 11/15/2013, 10:18 PM

Looks like a macro algae of some sort. Caulerpa, I think. I'd be happy to have a rock covered with those.

Reefer54 · 11/15/2013, 11:05 PM

You rock! thanks. It is definitely a neat macro...I'd love to see it spread, but something tells me that only the snail will be spreading it. Appreciated.

matmatoo · 11/16/2013, 02:42 PM

Hi everyone!

Well, today I rearranged my filter and was pretty astonished to find what appears to be a slug like creature living amongst my bio balls in my filter..

The thing was moving around when I took out a media sack and it appeared to be stuck to it - but I'm wondering what it actually is??

Thanks heaps in advance,
Matt
