5 foot Bristle worm discovered in a 40g tank

There not the most appealing to look at but in a weird way kinda cool at the same time, I got them in my tanks. They are considered part of the clean up crew. To me they are all part what's in the wild and have a purpose so I leave them be.

but that giant guy is still a different species then the ones we typically find in our tanks. Just look at the head of that thing.

The one is the video is a bobbit worm; a completely different "killer worm". They hide in caves/sand till a prey passes them and they just grab it at lighting speed; bristle can't do that

Found this in my tank a month ago. Funny thing is my tank has been up for 2 years. Nothing has been added for over a year and I dismantled all the rockwork 6 months ago. It's roughly 3 feet long.
