I don't really think that there are many people where that have kept this species in this forum.
What I do know about them is that they require a super big setup due to the size their colonies can grow to and a huge outworld space also due to their huge size and also often being referred to as "army ants" due to their swarming and raiding behavior. Not to mention that they will also require quite a bit of food, and they will probably require you to be invested in them monetary wise.
Don't take my suggestions as word to word because I know very little about Carebara in general.
Currently keeping:
1x Formica subsericea, 35-40 workers + maybe eggs *New* 2x Camponotus nova, one has only larva
1x Crematogaster cerasi, All workers is ded
*extreme internal screaming* 1x Myrmica ruba sp around 10 workers + pupa
*New* 1x Temnothorax curvispinosus, 101 or something worker + 3 or 4 royal mom ants + pile of white ant worms
*As you watch your ants march, remember that every thing begins with a small step and continued by diligence and shared dreams* -A.T (which is Me)
Sadly due to unforeseen consequences, I will soon be giving away my colonies (I will miss them though
)
