1. Build around the moult, not the decoration
Young phasmids hang from a branch and pull themselves free of the old skin. The Australian Museum advises providing enough space for them to hang about three body lengths above the floor or obstruction. That makes upper clearance more important than a chunky floor feature.
2. Airflow matters
Mesh and well-ventilated terrariums are commonly used because phasmids need airflow. A custom rear panel should therefore stay clear of vents and should not turn a ventilated enclosure into a sealed glass box.
3. Make food branches easy to replace
Fresh foliage is routine maintenance, not decoration. Use a stable water container or branch holder and close the opening around stems so small nymphs cannot fall into the water. A custom removable branch cup or disguised holder can make daily care neater without creating a drowning risk.
4. Keep the climbing texture useful and light
Thin bark-like texture, removable twigs and light branch sockets work better than heavy “rock ledges”. The insect needs surfaces it can grip, but it also needs open air around those surfaces.
5. Think about eggs and tiny hatchlings
Females can produce large numbers of eggs. If you plan to incubate eggs, make the floor easy to inspect and clean. Hatchlings are much smaller than adults, so enclosure gaps that are safe for an adult may not contain a new nymph.
