Pix & ID: Critters that come in your rocks: the good and the bad. - Page 207

Hey guys, sorry if this is the wrong thread to post this in but i recently found tiny critters in my sand bed. I've been running a 15 gal nano tank with two clownfish & rocks for about 5 months. They are a little larger than a grain of sand and slightly elongated. They have either translucent or brown bodies, its hard to tell because of their small size. I noticed them because I had a snail flipped over and saw they were covering him. I set him upright but suspect that he's dead. What could these critters be? Should I be trying to get rid of them? Any info helps a lot!

Isopods perhaps?

It might be a Collonista snail. These often hitchhike there way into our tanks via live rock, corals etc.

Hi everyone, I have a few hitchhikers I'm not sure about, even after going through this whole thread.

This guy opens and closes, and has a big thick rubbery looking foot. It doesn't move around.

Shot of it open.

And this thing might be a majano? It was on the live rock last night, and now it's on the floor of the tank and definitely moving, albeit extremely slowly. It has one little arm that's longer than the rest of it. Sorry it's not quite in focus. If you need a better picture I can scoop it out of the tank and try again.

Thank you so much!

This has nothing to do with sentimentality - many things wind up in local ecosystems that don't belong there like algae etc.. Take the above advice it is important.

WoW... digging that up ey? Well nothing gets flushed now just so you know.. anything that comes out of my tank now goes into the flower gardens for fertilizer.. If I could go back and delete that post I would but yeah we are on a lock out here after an hour or so.

Got a much better picture of the majano-lookin' thing. It's no longer moving. I think a starfish may have detached it.

Still not sure what the first guy is either.

Thanks again!

Hammer coral. LPS in euphyllia family. lucky you!

That was my first thought but then I went "no way. It has to be something yucky." Thank you for the awesome news!

reefbroao · 11/09/2015, 06:26 PM

What is this lil guy

Johnseye · 11/09/2015, 11:36 PM

Found this guy hanging out in my coral today. Never seen him before. What is he?

lolSam · 11/10/2015, 04:08 AM

What has started growing out of my live rock? I figured this was just a dead sponge but it's growing this white stuff and the tips glow under blue light. It has polyps now too. (Sorry if that's the wrong word, still learning!)

This beauty came in as a hitchhiker. Is it an open brain coral?

Caribbean Rose coral.

Nice score!

Bakerman · 11/15/2015, 11:06 AM

Can't quite id these guys. Have several, don't seem to bother anything. Pretty long, 2" or better. Super thin, white-ish but very transparent. Can't identify a head/tail/etc. Just a threadlike worm. Seem to hang out in pairs on the rockwork.

I adore this thread. I've learned so much from reading it.

Perhaps you can help me with this one? Surrounding the feather duster, the tiny white tubes with their tiny white (and a little red) heads? Hydroids? Baby jellies? Tiny feather dusters? They don't quite match up with google searches for any of those things, I I'm thinking something else I've yet to learn about?

whanieldang · 11/17/2015, 01:07 AM

i know this picture sucks, but i was wondering if you are able to see what i have drawn a box around and help me ID them? i just noticed them all over the sanded of my tank.

thanks.

Blurry, but Google amphipods and see if that looks right.

Taricha,

Would you say those are calcerous tubes? Prior to our new tank, I had zero interest in taxonomy, but now I am geeking out big time.

They are certainly not in as much of a tangled mass some in the pictures from this website, but I'm thinking the Sagebrush tube worm might be a candidate.

Found these small red stony blossoms on some of my LR when I was cleaning it. There was some black sponge or gunk on it so I brushed it up revealing these.

Also this is a good resource I found http://www.masa.asn.au/masawiki/inde..._the_Reef_Tank
