I got 2 of these...dont know to keep them or toss em. They kinda look like a slug with spikes? Not really looking like a worm but i dont know. They dont move much either.
Any Ideas?

Could be a nudibranch.

look like this?

 

[jvalason]

I guess it looks more like the one in the first pic then the one in the second. What is it and is it good/bad?
Another question....how do you post the picture on this board and not a link??

 

[dadummy]

it seems to be some kind of sea cucumber, I did a few searches and didn't find an exact match. I haven't seen it again since the picture.
where it says manage attachments, add the file of your pic.
the catch is to use PAINT
drag/drop pic to paint
click image
click sketch/skew
change the vertical and horizontal to 20%
click file
save as
then post

ive got one of these
its an abalone of some sort that managed to find its way into my tank
i took this pic about 3 -4 months ago when it was less than an inch big and since then its gotten to be about 2.5" or more

Mine dosent look that nice...mine looke like a black/brown leach or slug or something...

 

[murph145]

hmmm so it doesnt have a shell then?

 

[jvalason]

Nope... they dont really move much either. On the one in the picture you can see a whole in the back or front?? that it breathes out of i guess.

 

[murph145]

very interesting ... well just keep an eye on it and if nothing dont worry about it

 

[jvalason]

That's definitely a small sea cucumber. I have 3 identical ones in my tank.
