I think the AntHill X8 Optima is the most flexible package, as you have the vertical outworld-nest setup, but can also do the other positions the other setups can do.
This nest is pretty nice for my Pheidole, as when they get to a certain size, they can just explode in numbers overnight.
When you get to 50-100 workers and fill up a test tube, and transfer to this nest, and just open up one chamber and the corridor, that would be around two test tubes worth of space.
Then open up each section as you go.
According to the site, these can hold 15,000 4mm sized ants.... and at 3mm Pheidole minor workers, minus a few thousand for the queen and majors is more than enough
When I see others raising Pheidole with other nests, they have to keep adding more and more nests over time, and it gets messy.
Either it's too small or way too big for the colony
Plus I like the fact I can change from horizontal to vertical nest positioning anytime I want.
Although with the gypsum backing, horizontal would make the most sense, as the ants now have a nice surface to walk on, instead of the slippery acrylic, that some species have issues with
