Messor barbarus is a good choice as they're easy to care for (since they eat seeds and their protein needs can be covered with boiled eggs) and cheap in terms of food. They're also VERY active and large enough to be easy to observe.
HOWEVER there are a few things you should know before starting with this species.
- Get a small colony. Not a queen, a small colony. Single queens tend to be super susceptible to disturbance and you'll basically have an ant you can't even look at for 4+ weeks.
- Messor barbarus colonies can become MASSIVE. Not the "above 5000 ants" massive that some shops misleadingly say, more like 50.000 ants massive (that's A LOT more ants than it sounds). If you have the space, that makes them super cool. If you just want a small colony in the corner of the room, get something like Formica fusca or Camponotus japonicus instead.
- Messor barbarus, once grown beyond a few hundred workers, will absolutely DEMOLISH their outworlds. They will carve out the substrate, build lots of small anthills, cut artificial plants to pieces, untroot or bury plants, place seeds and water them so they may grow into little gardens, etc. and generally leave no stone unturned. They're the McGyvers of the ant world, all you can do is give them materials to play with and watch them going bananas with them. The upside is they will pretty much always be busy with building or reshaping something.
- If you use transparent tubing avoid 180° turns. Messor barabarus workers tend to navigate by using light sources and a u-turn might confuse them (i've seen that happen to someone in a journal). If you can't avoid a 180° turn just cover either the part before or after the corner to block out the light (that's what fixed the problem for the guy who had workers running back and forth before dropping their seeds at the turning point).
- Oh, and their poo is very oily and they love to crap all over the nest inside walls if the nest is permanently exposed to light. If you give them a small extra outworld they may use it as a toilet and spare the other parts of the setup.
Well, if you're cool with all that, have fun, they're absolutely great ants (Messor barbarus most likely the most popular pet ant species in Europe for good reasons).
