I've done very little this month, but the terrarium still looks great. Plants are continuing to fill in and the water/lighting combo seems to be just about right. (I do have a "dry" spot on the upper middle, but I'm waiting to see what continued plant growth might do to resolve this.)
The springtail population is still doing great. My courageous decision to do nothing to help the isopods seems to have paid off as well, since I can now find them very reliably just below the surface of the leaf litter.
I'm still on the lookout for a good source of Ranitomeya variabilis "Southern"
, but no luck so far. Not in a hurry at all.
