I have some Hitchhikers

[Calistmo]

One of various small worms in my substrate. The other ones I couldn't get video of and are also very small.

Anyone know what this is?




Here is a picture for scale

No clue, that’s weird... @Colin_T @CassCats

Here is another worm. It's really hard to focus!

First one is a Rhabdocoela flatworm--harmless

Second is a type of detritus worm, also harmless.
