New hitchhiker found, I don’t know what it is

[willforr]

I just found a new hitchhiker in my tank today. I don’t know what it is, it kind of looks like a worm, but it’s very small. If anyone needs to see another picture let me know, because I know the quality isn’t the best. Thank you

I can’t say for sure, but it appears to be a young bristleworm. There are probably a lot more. They are harmless.
