Small hex needs venting, purchase 1 or 2" vent.
1-Small Hex, plastic lid
Small hex size: 4 x 6". Here is another hexagon for your mantis needs. This container is great for small nymph group housing too. As you can see it has 5 sides you can turn it onto, 6 including the lid. I like this feature for mantis that are molting, if the mantis is apparently in the wrong position you can turn this hex to help it without disturbing the mantis. This size hex is good for medium to small mantis and spider caging or any other insect that needs a large home. Feeder hole included with plug, container needs venting.
