Cohabitation with millipedes

[Maniae Ophio]

I’ve got a large Cohabitation Enclosure made up of Dubia Roaches, Tropical Grey/Orange Woodlice, Darkling Beetles, Fruit Beetles, Springtails & Earthworms, Would Millipede’s work with neighbours like this? Or would it be too risky for them?

i’m not planning on breeding Millipedes btw i just wanted to create a big “eco clean” enclosure

Def too risky- isopods dont do well with millipedes.

Ah i see, what species do you think would work in a set up like this that isn’t a millipede then?

I think you have a whole gang there already haha!

Is that just in captivity? I’ve seen them under the same log/rock before in the wild not that they cohabitate in wild .

The main issue is size and availability of resources. In a forest of many acres, there's enough space and food to go around for multiple types of detritivores. And if one species is bugging another too much, there's always another log or rock they can go live under. In a terrarium this is not so. There is a very limited amount of food and shelter, and these things will always constrain how many animals can cohabitate happily in your terrarium.
In one of my first large eco-terrarims, I had greenhouse millipedes, rough isopods, common pillbugs, dwarf whites, and powder blues. Now all I have in there is powders and dwarf whites, they completely outcompeted the other species and drove them to extinction. That's what it looks like on the macroscale, but on a smaller scale, it looks like isopods eating moulting millipedes and millipede eggs, crowding them out of good hiding spots, and getting to food sources first and eating them faster.
TLDR: The most aggressive species, such as most isopods, will always out compete less aggressive species, like millipedes.

What a pain , then you need something to eat the isopods. Adding more confusion and complexity. I used to catch the spiders specifically that ate them.
