A few people have asked if there was going to be a smaller version of 'The View' for smaller ants. Well there is and it has been in testing for some time and is ready for release. http://anttopia.com/...&product_id=80 Hope you all enjoy.
I have housed tapinoma sessile in one similar now for some time. The queen is happy and new eggs are abundant, and best of all there have been no escapes that are preventable. They are very good climbers and required a lip around the top with a barrier as well; as I use a extra virgin oil barrier. And they scaled it pretty well. But with the help of those ants, I know containment should be easy.
