Couple more ID's

Yellow worm like thing... doesnt look like a bristle worm.
I also dont know what this little grey thing is...? Has like 20+ little legs.
And lastly I took a better pic of the spiney thing next to my mag-float.

 

[raseri]

That last one kinda looks like a little sea urchin. I know someone that got one on a piece of liverock that they bought. So maybe?

 

[bang guy]

The Yellow Worm looks like a Bristleworm to me.
The Grey thing on your magnet kinda looks like a Sea Cucumber.
The spikey thing looks like an Urchin to me.

 

[cableguy]

Thanks guys... Im not sure about the bristle worm, but everything else does looks like what you guys said. I will keep looking for a bristle that looks like that.

 

[hunt]

the fourth kinda looks like a majano, but the pic is to dark for me

 

[cableguy]

Def not... I can post a pic of one I am about to kill it you would like. I know 100% that it is not one. I've killed about 20-30 of those so I have a pretty good idea.

 

[hunt]

, the pic just looked kinda like one to me.

 

[spanko]

Would like a better picture but #4 looks like a feather duster to me.

 

[handbanana]

I agree with spanko. Looks just like mine.
Does it retract into the rock?

 

[cranberry]

Looks like a pest anemone to me. The central disc looks solid.

 

[handbanana]

you have a good eye Cranberry. Im still new to this so I wouldnt know what a solid central disc looks like.

The genral shape looks like the little duster living in my LR tho.
Also I just learned there are other pest anemones than Aiptasia. Even worse ones.

 

[cableguy]

Uhh maybe but it didnt look like one at all. After looking it up, it looks like a Urchin. It was also on the bottom side of the rock.
