Blue Dream Shrimps from Ebay.. kill or treat?

[Box of Demons]

What is this on this shrimp? should I be worried? Treatable or should I euthanise immediately. I have put this one in a quarantine tank but that inside my main tank...

Any help or advice appreciated.

That looks like Detritus worm / Planaria to me.
It's funny because I just had detritus inside my shrimp tank today & I do some research & get help from member and it turn out its harmless.
Different story if its planarian, planarian will hunt Shrimp & Snail Egg apparently the best thing to do is identify if it is a Detritus worm / Planarian

leeches.
add 2 heaped tablespoons of rock salt for every 20 litres of water. Keep salt in there for 2 weeks.

Willit affect my fish and nerite snails? Is it safe to leave?
