Another "Flatworm?" thread

[Tristren]

Hi there,

So I got a Sinularia a few days ago, and today saw this:

Not a great picture. It's moving around a bit (not when I'm looking).

Is this one of the flatworms I hear about?

I'm no expert but , it does look like a flat worm

Looks more like a polyclad flat worm. Quite nasty. Not like the acoels or others. Get it out like yesterday.

What's the best way to do that?

And what do they do that makes them that damaging?

Edited my post.

Thanks. Will search for it again now.

Edit: having said that, I think the Sinularia it is on is covered by a light brown film. And that the flat worm in question seems to have been eating it.

Would that make a regular white flatworm look brown like this one?

Because this is uniform with a "smooth" edge. Whereas the leopard polyclad in the article was mottled with an irregular shape.

Is that good? Bad? Depends?
