Large flatworm id?

[Dark_Reef]

My wife spoted this in one of our displays today and I needed to break open the live rock to get it out.

I looks to be about 2.5 inches.

The common polyclad. A snail eater. I have them too.

 

[Dark_Reef]

I found one does that mean that there are more? What other problems can they cause other then snails?

They eat clams as well.

 

[Dark_Reef]

Have they ever been known to eat any sps flesh? I have a red planet with some interresting parts of flesh that keep disapearing.

I think, it´s a Pericelis sp.
They can eat snail´s and clam´s.

 

[Joe Pusdesris]

It is common for there to be more if there is one.

they are large and slimely, eat clams and snails. To find them pick up the rocks sitting directly on the sand and look at their underside.
