Found a couple of these hanging out in my sump. Can you confirm if I should keep them or discard them. They move awefully fast for a starfish.

Definitely keep them, highly beneficial!

Very cool! They're mini-brittle stars. Do you have any idea where the hitchhiked in? I'm thinking of ordering some from Indo Pacific farms. http://ipsf.com/ministars.html

So this little guy came creepin out of one of my (his?) rocks last night. He's quite mobile. Looking around I think it's an Urchin? has anyone had any experience with a hitchhiker as such?

I am astonished at all the hitchhikers I've been running across lately. This is my first tank and I am loving it.

One concern I have is that I dont want anybody munchin on him when I add my cleanup crew.... will a crab or shrimp harass him?

Thanks everyone in advance

taricha · 07/22/2015, 08:50 PM

Almost nothing messes with urchins. I wouldn't worry about his safety.

Grizz717 · 07/23/2015, 06:30 PM

Anyone know what this is?

Can you get a picture without the blues on?

Bakerman · 07/25/2015, 11:36 AM

Any ideas? Lurking in the sump.

Looks like a peanut worm. They're detritus eaters and, I think, harmless.

Dotterer · 07/26/2015, 09:02 AM

Hey there - came home late last night and wanted to check on a RBT that I had put earlier in the days, so turned on just the blues and saw this beast!

Here's a full movie of it moving around.

Sorry I didn't cut the blues and move to white - wasn't thinking while I was filming.

Any ideas?

It's a harmless stomatella snail.

Hello! This is my first post. My husband and I are about a month into getting our 125 gallon aquarium going. Right now, it's mostly rock and two tangs. Last night, I took a flashlight to look for hitchhikers. One little cutie that I found is apparently an Australian Tubeworm. In the wild, this is an "invasive" species, but I haven't read anything bad about it in terms of aquariums. Here's a (bad) photo. Should we leave it alone or take it out? Thoughts? Thanks!

Mrs4444 · 07/27/2015, 09:08 AM

Wow. That's really cool! I'm just a beginner, so I find this especially interesting. Thanks.

Mrs4444 · 07/27/2015, 09:11 AM

Wow. I can't believe that I'm one day into this hobby and can answer your question (I think). I just this morning researched one of these in our tank. I THINK it is a Ficopomatus enigmaticus (Australian Tubeworm). I started a thread this morning to ask if we should remove it or not, because many sites called it harmless, but I guess it's invasive in the wild. Let me know if you find out otherwise...

Thank you so much!

Karliah · 07/29/2015, 09:42 AM

Any idea what this is? Came on the live rock I got last night. Slightly deeper color than in the pictures.

cloak · 07/29/2015, 10:03 AM

Foraminiferans most likely. (harmless)

Im sorry I have no idea where they came from. Just showed up suddenly whats seems out of no where.

Goldmund · 07/29/2015, 08:55 PM

Hoping I can get an ID on some stuff that's been popping up in my tank.

This is covering the underside mainly of a few rocks.

These little guys are all over, but I've never seen them do anything.

Bubble algae?

And the dreaded aiptasia

taricha · 07/29/2015, 10:03 PM

First I think it's a clear sponge. Body shape more irregular than tunicates usually are.
2nd is vermetid snail. Some people (me) find annoying, but not a big deal.
The others I agree.

raven312 · 07/30/2015, 07:12 PM

This guy came in on my rock, though it wasn't visible at first. It's starting to grow now, but still pretty small. I get the impression it's a finger leather but I can't be sure:

(I have to work on getting a good close-up). I'd mentioned finding "purple flower-like" things on one of my rocks, now it's growing all over the rock. I hope someone can see it and help me ID.

Are they a coral? If so, they look like they're going to try to take over.

taricha · 07/31/2015, 06:16 AM

First thing is so small in that pic it could be anything.
Second, those look like tiny feather duster worms. If so, they'll retract into the rock when threatened.

raven312 · 08/01/2015, 04:24 PM

In doing a LOT of digging, it appears that I have blue star polyps (ALL over the place!)
