I'm not sure if this is the correct section for this thread, but the site seemed primarily aquarium-oriented, so I wasn't sure of this should go to the Substrate section. I still consider myself a complete newbie to this site, so please correct any faux pas on my part.
I made
this post regarding millipede tank drainage layers nearly a year and a half ago. Sadly, my grand plans for a terrarium were put on hold due to having a an barely-insulated apartment with a mold infestation in the walls. However, I am now out of the moldy, 85 degree deathbox, and can resume my quest for a millipede terrarium.
To summarize the progress made in the previous post I made, I plan to house
Dendrostreptus macracanthus, possibly some
Macrolenostreptus brachycerus, and the usual pillbugs in a planted 10 gal.
The temperature will be around 75F, and the humidity at 60-70%. For plants I'm thinking a small ficus, creeping fig or pothos, pilea, and mosses.
Now for the question:
What kind of soil mix should I be using for this tank? Coco fiber is pretty standard for millipedes as far as I know, but I assume the plants won't like it without something else added.
