Reeeeally LONG WORM in a 20 gallon tank

[GoFish]

If it was a bristle worm wouldn't it have bristles? I know it's not the best photo, but it has distinct rounded L shaped legs that move like a millipede. I have a bristle worm in the tank and they look like totally different species

I'm sure trout would love it! But the trout aren't feeding right now in my area, and I don't really wanna put it on a hook until I know if it's safe to touch
