Id help...bristleworm? and a green spot

[cam2fst4u]

First Pic:
I saw this crawling out of a rock this eve I think it is a bristleworm but I never seen one while the lights were on before.

Second Pic.
I have no idea what this is. When I bought this rock I didn't notice it until after a few days in the tank. Started off as a lil spec and now is more of a spot. It looks like a bright neon green or something and it is growing. What could it be? Sorry this is the best pic I can get right now.

The first one is definantly a bristle worm. I have hundreds crawling around my rock work after lights out.

Not to sure on the second one though. Hard to tell looks like a blurry spot:grumble:

Just keep an eye on it and if it gets bigger or more defined, let us know

 

[cam2fst4u]

I thought it was but just wanted to be sure.

The green spot I have tried to get a better pic of and that is the best one so far If I am able to get a better pic I will post it.

+1 Brian for the worm

The green spot almost looks like some Green Coraline...does it look like it is protruding/bubbling off the rock or does it almost look like your rock is just stained lime green; if it's the latter than it's just coraline, I know it's a strange color and you obviously have some purple in there, but I've got some green & purple in my tank too.

It looks like it has holes in it. and it is growing off the rock whatever it is. would it be possible it could be some sort of a sponge maybe?

 

[AdeptMrSniffles]

I'd say it's just some yellow sponge. That's what it looks like and from the description of it being holey that kinda confirms my opinion. Is that teal coraline in the first pic? If so... that's awesome.

i would also say sponge. leave it.its harmless

 

[dcantucson]

I would say please post a closer up picture of the yellow stuff.

 

[daugherty]

i think it is some kind of sponge

 

[cam2fst4u]

Ok I just got back from running a few errands and checked out the tank and most of the spot is gone from where it was and is now on top of the rock kind of floating? I have tried to get a better pic but thats the best one I have gotten so far.

 

[dcantucson]

So it's moving around? Maybe it's a type of nudibranch?

 

[cam2fst4u]

It wasn't.... Im thinking maybe one of the hermits or shrimp got it. :confused:

 

[dcantucson]

The mystery continues.......
:lol:

 

[KidJ57]

well at least you can definitely mark coraline off your list :lol:

Brians got the bristle.
And everybody else has the sponge covered:D

That greenish/yellow spot in the first photo looks exactly like my tunicate. I've got a big blob near my zoa's and a few spots that look just like yours on my LR. Hope it's ok?
