Yes, stomatella. I love the black ones.

Is this why my zoas are closed up? Caught it right on the tip of one of them! Not going back in the tank but if there are more (likely as my zoas don't look happy!) any ideas on how I can get rid???

I found my blue star on the sand bed this morning, which is odd because she's usually attached to the glass swinging her arms around. But I found this crawling on her. Anyone know what it is?

Thanks Kimberly! ALL my zoas are closed today this thing can't have been the culprit for all of them???

 

[Crooked Reef]

Not sure if this will post but is this an aiptasia? It's what it looks like to me but it is small so I wasn't sure.

It is possible I missed this thing somewhere in the 128 preceding pages but what is this thing. It looks like some type of worm that has little tentacles coming off of it. It buries itself in the sand and sticks the tentacles out. It almost looks like a tree root.

It's a spaghetti worm - harmless detritus eater.

Any idea on what this is moving in my sand bed. It looks like a brown moving spider Web . I can visible see it moving each individual hair like string through the sandbed. You have to get really close to see it moving.

Spaghetti worms. Nice... Some people pay to have those in their sand.

Thanks for the help. Didn't see it being a positive thing.

 

[worm5406]

Without a doubt a good thing. Just so long as it is on the sandbed and away from polyps or sensitive items.

 

[adakin]

Any idea what this red guy is? Sponge maybe? He has grown quite a bit in the past few weeks.

 

[SushiGirl]

Looks like some type of algae.

Can you tell me if I'm even close on critter ID here please?

Tank has been set up since 2/8/14. Live rock/live sand from LFS

No idea of the yellow stuff"¦ it wasn't there yesterday.

Any idea what kind of green macro this is?

The yellow circle a polyp of some sort or baby majanos?
Pink circle a tube worm (they have black or flesh colored tubes) or a feather duster colony?

DSCN0958 by nometank, on Flickr

The green circle is a red macro algae?
The orange circle - a majano, aiptasia or polyp of some sort?
You can see the tube worm? (or feather duster maybe?) from the side here, same rock as the above pic.

Thank you so much for playing, "Guess my Critter" :lolspin:

LadyDave,

It might be the reason your zoa's are closed, but if so, it's probably because it's been crawling around on them, not eating them. Your snail is a Wentletrap, or Epitonium. They are parasitic on anemones but usually don't kill them.

Cheers,



Don

What is it???

 

[Flashy Fins]

Spotted something strange swimming around in my tank tonight. It's mostly clear and swims at a pretty good speed with jerking motions that propel it. I watched it swim into a plate coral that seemed interested in eating it, but it escaped. I sucked it up with a turkey baster and put him in a cup with some tank water to take pictures, and it started crawling along the surface like a slug, rather than swimming as it had in the tank. It seems to be able to change form and move in various ways. A few pictures:

It's very tiny, about 4cm long when stretched out. Is it some kind of flatworm? Never seen anything like it in my tank before.

 

[Flashy Fins]

After spotting more of them in my tank and browsing the web for clear flatworms (my pictures make them look colored, but they are primarily clear), I think they are Amphiscolops flat forms, supposedly harmless.

Looks like a green algae film to me, but hard to say.

Any idea what kind of green macro this is?

This is Bryopsis, and you do not want it in your tank - I would remove the rock it is on and scrape the area clean, making sure no part of Bryopsis gets into the tank.

The yellow circle a polyp of some sort or baby majanos?
Pink circle a tube worm (they have black or flesh colored tubes) or a feather duster colony?

Yellow: Protopalythoa sp.
Red: some soft coral, we call it "Cervera sp." - but I'm not sure it is one... see this (German) Link: http://www.meerwasser-lexikon.de/tiere/2365_Cervera_sp.htm

The green circle is a red macro algae?
The orange circle - a majano, aiptasia or polyp of some sort?

Orange: hard to say, might be some jelly fish polyp (hydroid) or something else
Green: yes, a red algae species, shouldn't turn into a nuisance.

After spotting more of them in my tank and browsing the web for clear flatworms (my pictures make them look colored, but they are primarily clear), I think they are Amphiscolops flat forms, supposedly harmless.

I agree that it's a flatworm, as you said; most non-photosynthetic and smaller ones are less of a problem in reef tanks.
