Sorry Jack and others for my late reply, but I am very busy at work.
I keep now all my acuminatus and spinosus in couple's in the Exo-Terra PT2646, that are the biggest screen cages they have. Well planted, with lott of moss, branches, dead leaves,... I have always some spare terrariums left for the reason that Benny is telling. Some animals you can keep always together others they have to be separeted when gravid or for others reasons.
Jack waht kind of lighting/heating do you gone use?
Best regards,
Tom
