Looks like flatworms to me.

I have tryed dipping them in coral rx, seachem coral dip and used a treatment with salifert flatworm exit in a bucket but nothing seems to afect them..

 

[alexjoha]

I have just tryed to test dose in a cup to see if it had any effect on the flatworms.

I did the following:

Glass with 40ml tank water.
2dropps of salifert flatworm exit (exp.date 2018)

Put 2 copepods in the glass
Put 2 of the flatworms in.

Result after 1 houer:

Copepods died instantly

Flatworms still living and going arround.. ill let the glass sit over night to see if the bugger still lives..
