Slug? Flat worm? Nudi?

I found this little guy on the glass hiding behind red ogo. This pic was taken a couple hours after dosing Prazipro for the second time. I tried looking at it from the top and side and it appears flat, no shell that I can see. Do I need to eradicate and keep an eye out for more?

Flat worm

I'm sure other will reply but I'm positive it's a flatworm, and I'm pretty sure that type is harmless. I believe it is a ghost flatworm.

Is it a bad sign worms like this are still alive after two doses of prazi? Makes me wonder how the parasites I’m trying to get rid of are doing...

I'm not sure prazi will work on flat worms. Probably need flatworm exit for them
