Help ID these pests ASAP!

Hello Everyone,

I just noticed these little "slug like" creatures making their way across the front and side panes of my tank.

What are they? Are they an issue in my tank? What should I do? Is there something I can use on my mixed reef to kill them?

Please help ASAP. Thank you in advance.

They look like Flatworms to me

Looks like flatworms to me too. As pointed out above, check out Flatworm Exit from Salifert to kill them. Follow the directions perfectly and you will be ok. Luckily those are "ordinary" flatworms and are easy to kill, not the dreaded acro-eating flatworms.

those are flatworms. how is your water quality? -- that can spur their growth/numbers.
they are harmless unless in large numbers, just not very attractive. there are many fish that will eat them as well.

yep flatworms. I had a H. Melanurus wrasse that made short work of mine, though it's not guaranteed they'll eat them.
