Looks like an AntWorldUSA formicarium. Which is the brand I use to keep my Tetramorium in (yes, these are the Tetramorium that destroyed the Fluon, ate the olive oil, and are now contained with mineral oil). However, the climbing wall goes right up to near the top so I'm a little concerned about escapees.
Personally I would go for Camponotus but Tetras are definitely hardy and easy to keep.
