Anyone know what these slug looking things are?

Noticed them in my 80L tank this morning. Anybody know what they are and if they are harmful?

Right off hand they kind of look like snail leeches.

Removal by hand or wormer meds like pancur or planeria zero.

They will eat snails.

Ah, I wonder how they got in there! I haven't introduced any new plants or fish in that tank in ages...

Will any fish eat them? I was already considering moving over my apistos to that tank, so wondering if I should just expedite that transfer....

Do you feed live food?I find them in my blackworms.

The fish may eat them.

I do - brine shrimp / bloodworms and the like. Must have come in on that then! None of my other tanks have them, and I'm constantly taking clippings from the 80L and putting it in other tanks, so the fish must have eaten them in the other tanks.

Thanks
