I went with an attempt at bioactive, with basically the same substrate but I added a couple plants.

Awesome that you’re utilizing live plants - we plan on doing the same with our next milli tank

I have a feeling she ate them

Probably ha. Nature is flexible and opportunistic

Would isopods compete with the millis?

While some species of millipede and isopod should be capable of coexisting in theory, I wouldn’t take the risk myself. There are many protein-driven isopod species that would likely have no qualms munching on a millipede while vulnerable during a molt. Even isopod species that aren’t necessarily protein driven are still opportunistic feeders. It’s just asking for trouble, as well as complicating the husbandry.

If you have or wanted to make a post about your critters I think it would have a warm (cold) reception. I, for one, would love to see more Thanks for the reply! It made me happy

I’m glad! Maybe I’ll make a post about our collection somewhere at some point :)
