Hi, I'm Bill from the UK, and these are my display Vivaria.
First is my setup for a small group of Loboptera decipiens, this lives on my bedside table and measures 8" x 8" x 8", and uses all live plants except for the reindeer moss. There are hollows in the substrate that are filled with reindeer moss and leaf litter, and the roaches spend the daylight hours here except at feeding time. The temperature is kept below 21.5 Celsius and the humidity at around 70% RH, which is more humid than many others choose for this species, but mine were very lethargic at 50% RH. the vivarium has LED lighting on a timer.
Next my Polyphaga obscura Vivarium.
