Bought this dechlorinator today from an offline dealer today. Is it safe for my neo caradina shrimps?

Hi everyone,

I found this worm in my shrimp tank today and I’m a bit worried. I usually see detritus worms that are thin and white, but this one is darker and has a very distinct "wiggly" swimming motion.

A few observations:

• Head Shape: It doesn't seem to have the classic "arrowhead" shape of common Planaria, but it’s hard to tell for sure.
• Color: It’s darker/brownish rather than the usual translucent white.
• Behavior: It was swimming mid-water/near the surface (as seen in the video).

I’m really protective of my shrimp colony—is there a species of Planaria that looks like this, or could it be a different type of Oligochaete/leech?

Any help identifying this would be greatly appreciated! I want to know if I need to start treatment or if it’s just a harmless scavenger.
