Love decorator crabs. They are as bad as tux urchins.

Lucky you! My orange one never would. He'd always go back & get new zoas...orange to match himself of course! I'd bug the crud out of him by putting his molt in front of him over & over LOL. My maroon one preferred sponge & didn't have nearly as much personality as the orange one.

Sugar, at least the urchins take the whole frag instead of cutting their own!

One crab like these (like the white one but slightly more "hairy") came with a new piece of rock here, I just saw him the day when I added the rock and 2 days ago, almost 2 weeks after that. It is pretty hidden in some big rock I have I guess (I only see it there), and I have never seen him walking on the substrate or somewhere else but today I saw a zoa polyp floating in the tank all by itself... although it seems a zoa from a different kind of these I have, it might have been cut off by this little crab which is the only critter I (think) I have that could do it (my stenopus never touches the corals). As there seem to have some extra food for it, it is not attacking my corals (so far). I won't remove it unless I see/notice it eating something.

Looked through everything didn't see this before. I think it is some kink of macro algae.
Second picture I'm wondering about the red stuff growing between the zoas upper left side. I hope it's okay because it is popping up other places.

Hi all, please help ID this brown thingy that seems to take over my tank. How do I get rid of it? Thanks in advance.[IMG]

Look up cyano bacteria.

Look up flatworm. There are different ways of handling them.

Thanks, but cyano looks to me like wispy slimy stuff. This looks like I need a little red lawn mower to cut it back. Sorry for the bad picture. Maybe I can get a better picture.

nanoreef heaven · 10/25/2012, 03:23 PM

If you can pull it off in chunks its more than likely cyano.

Janetora, cyano can take on different appearances. Your pic is too grainy to tell.
Not sure what the first one is.

MortenB · 10/26/2012, 11:12 AM

Can someone please help me ID this slug-like creature? Not the best picture, but hoping it's good enough.

Many thanks, M

nanoreef heaven · 10/26/2012, 11:17 AM

Can't see good but look up stomatella snail.

I've decided that I think the first picture is Gracilaria arcuata. I stumbled onto a picture when I was reading about macro algae for a sump. http://marinefiends.com/wordpress/20...ro-algae-care/
Or not

Joshporksandwic · 10/28/2012, 10:16 AM

Hello! Anyone knows what type of slug this is? Is it reef safe?

Joshporksandwic · 10/28/2012, 10:20 AM

sorry double

Sk8r · 10/28/2012, 10:28 AM

Put it in your sump. If you have zoas, I'd suspect that's not good. Most things are safe in the sump or fuge.

nanoreef heaven · 10/28/2012, 10:29 AM

Thats crazy looking.

*Sent from my little corner of the reef. Nano nano!*

LeslieH · 10/28/2012, 11:23 AM

It's an opistobranch sea slug, a species of Elysia. They eat green algae so corals & zoas are perfectly safe.

It's a harmless species of polychaete worm in the genus Amblosyllis. That body shape is very distinctive.

Thanks for the ID! Glad to hear it's harmless. I have not seen it since the night I shot the photo.

redmage · 10/29/2012, 09:52 PM

I have this growing on my live rock can anyone tell me what this is?

nanoreef heaven · 10/29/2012, 09:53 PM

Can you describe it. Kind of hard to see clearly.

*Sent from my little corner of the reef. Nano nano!*

redmage · 10/29/2012, 09:56 PM

it is brown and looks like a fan... it has a main trunk with little branches it is about 1 cm to 2 cm tall.

I really need to get a better camera.

nanoreef heaven · 10/29/2012, 10:04 PM

Hmmm. I thought it look like hair algae but u said it has a trunk. If you can get some better pics that could help someone identify it.
