Pix & ID: Critters that come in your rocks: the good and the bad.

You can put the rock right back in. The glue gel will harden underwater.

Sponge?

I put a piece of shrimp for my hermits to pick at and A LOT of bristle worms came out the rock and started eating it. I thought it was awesome, I know most people don't want them in their DT but I don't mind, I like them. =]

I have a few hundred bristle worms. The longest I have is over 8" too. They are good in all the small cracks of the rock and clean it out just like a pipe cleaner.

I thought this was a dead coral skeleton but tonight (a little over two weeks after cycle completed) I noticed it's alive! It has neon green arms coming out of the outer ring and what looks like a mouth in the middle.

Any idea what it is. The skeleton is hard.

No way to tell without a closer shot. Could be any number of LPS.

I agree, but just in case it's a non-photosynthetic lps you might want to try to feed it (a small piece of mysis every few days or so), you'll see if it takes it.

Hey guys. I was just wondering if anybody could help ID what I have here. There's a couple spots where they are around my tank. They appear to be black/white striped that stick out from the rocks. Sorry, I know the picture isn't the greatest.

 

[hogfanreefer]

Looks like a brittle star leg to me. And I think there's an aiptasia just up and to the right of it.

 

[Rob in Puyallup]

Yup, brittle star. I have several in my nano tank.

Okay folks, how about this?

Going to do some research, found it on some coral I just got!

 

[Rob in Puyallup]

I also have some tiny Sun Coral polyps that suddenly showed up on this bit of skeleton which was purchased with live rock rubble...

Here's one of those brittle stars. He's in amongst the zoas in this photo. Left middle here:

Thanks Sushi! It definitely is an LPS?

Here's a couple of slightly better pictures I took today (with my contacts in:lol2

With flash

Thanks for the ID on the brittle star guys. I was trying to figure out what kind of worm it could be and I never thought that it could be a star. And by the sounds of it they aren't bad critters to have in the tank.

So what are these white tentacle like things I'm seeing stretching out from holes in my live rock? They stretch out in groups almost like a squids tentacles from a central hole in all directions.

 

[cloak]

Probably a harmless worm of some sort. Check this out.

[Kentech5]

Yep that looks like it. Thanks.

Tacos, I can't get your vid to play. As a guess (since you named it "snail") maybe a stomatella, a collonista, or a pyramid snail. I have pics of all of those on my Homepage (click my name & pick Homepage) or you can google them.

Hogfan, maybe a baby plate coral?
