rule of thumb: The minimum size for mantids is easy to define on your own:
- Length = Width = 2x Size of the mantid
- Heigth = 3x Size of the mantid
Also for keeping groups of mantids for communal species, if possible, minimum sizes should be followed to avoid stress for the animals. Terrarium Generally every container with enough ventilation (s. "ventilation")can be used. The most beautiful are glass-terrariums. Sometimes small glass-terrariums with two ventilation areas are available. The ceiling should be covered with fly-screen or fine mesh, so the mantids can hand from it. This is very important for molting.
The least expensive and easiest way to keep mantids, especially when you have more mantids, are plastic containers. Recommendable are 5 or 6 liter boxes.
