Slug like creatures creeping through my soil?

[tyrophagus]

Ok so pond life happens and hopefully only in a healthy tank but what on earth are these creatures. I introduced some new plants 2 days ago (related?) and today I spotted a fast moving slug - its very fast for a slimy creature! I grabed my phone and took a video that is blurry in parts. While recording I saw two of them together - now if you actually try find them they are impossible to find so this must be coincidence.

Are the dangerous to fish?

What are they?

Thats exactly what they look like - thanks mate

"planarian." The Columbia Encyclopedia, Sixth Edition. 2008. Encyclopedia.com. 24 Jul. 2010 <http://www.encyclopedia.com>.

So no danger to fish? Not a sign of imminent disaster in may tank?

should be ok with fish.maybe not shrimp.

If they are planaria then they will be harmless to absolubtly everything.
Are they flat (as in, paper flat) or a rounded shape in the body?
They look to thick and much to fast to be planaria in my eyes.

Hi all,
Does look a bit speedy, but it is probably a Planarian. Have a look at its head, it should be arrow shaped with 2 little black eyes, like this - :>. They are very easy to catch, put something meaty (like a peeled prawn) in an aquarium net at "lights out", and come back an hour later and remove the net, prawn and Planarians.

Yep. Flat and has a head that is arrow shaped. Amazing what appears in a tank.
