Small flat worm?

Anyone know what this is. Took like 10 off my frog spawn today.

It is unfortunately a flatworm, indeed.

There is a lot of information about them, how to identify the exact type you have as well as different eradication strategies available online. I highly recommend you to read over the different approaches and plan this out, you'll most likely end up doing weekly treatments for a couple of months to completely eradicate it.

Good luck!
