Hi everyone,
I've recently become very fascinated wuth detritus worms and want to learn more about them and their life cycle.
Yesterday I put a manzanita branch into my betta tank. Today I noticed a couple of detritus worms on it and thought nothing of it, because why would I? But then I realized... these have to be new detritus worms and thus must have just built their casings... or maybe they are still building them! I looked, and sure enough they were wiggling around, appearing to grab...detritus... and it looked like they were pulling it back or maybe eating it.
I took a short timelapse that just shows a couple of them wiggling around on the branch and uploaded it here if you'd like to watch it.
