I was looking in on my worms after ignoring them for 3-4 days (I'm getting better at that) and didn't even notice this while checking out my tower and the Nursery. Took me a minute to grasp all the color I was seeing in my breeder bin and what it was! Guess there was some active spores left in the substrate!
Shot the video and then looked at the other nursery. That's the still photo!
What an adventure!
