Not much of an update on the Hypos but rather their food. My springtails I bought aren't doing to well (but I think I saw a baby??) so I took 6 and put them in a hydrostone setup. Hopefully they breed and can keep the culture going. I caught some springtails outside and put them in a charcoal setup. I also made a culture of springtails from my isopod setup. I'm feeding all my springtails nutritional yeast, long grain brown rice, and fish flakes. Hopefully out of all of these some succeed. My booklice are mostly gone and once they die out I'll probably never get another culture of them again. Sorry if you were hoping for an actual update.
If anything keep the bought springtails in charcoal and move the wild caught to a hydrostone. Most wild springtails can't stand a setup as wet as a charcoal bin.
