Assuming it’s a slug or flatworm, but not sure which. Can anyone identify based on this crappy video alone? It was found in a tank with millipedes and springtails. I have moved the millipedes out of the tank into a quarantine area until I know if this is a treat and the tank needs to be treated (substrate baked, wood boiled, exc.) Only want to treat as a last resort, I have a great colony of springtails living in there.
