Found dead in tank

I found about 5 or 6 of these in a corner of my tank dead any ideas?

 

Looks like some sort of worm, unfortunately that is the best I can do.

 

Thanks 2in10 hopefully corailline can give me that helpful link *nudge nudge*

 

yeah im at a blank here..its 100% dead..

 

Can you put more water in the cup so it's kinda floating & easier to tell the features on it, or did you already trash it?

happy hunting

 

Thanks everyone and sushi girl it was already trashed when I pulled it

 

hmm very strange.

Remind me again how old is the tank? Did it just cycle?

The images could be so many types of worms. Why they would die I have no clue. A predator would have eaten them.

Interesting.

 

The tank is around 3-4 years old, I just had to down size it when my father in law gave it to me, but I found out from a friend that has a coral propagation green house and he said it is a flat worm of some sort. Could that be it?

 

So many different type of flatworms. It does not look like any flatworms I have seen. My experience with flatworms is that they not no appendages like bristles, spines, growth like protrusions and that image looks like they do ( might just be me). I will have a look around in my books and a couple good sites I know of, now that you have cleverly peaked my interest. :
