Have to say Fleur, am very impressed by your research into this, so many people come on here having already ordered a species, with absolutly no idea what they are getting into, and its very frustrating!!
If you are interested in ligniperda (bearing in mind they require hibernation) you may also like Camponotus herculenus, they are beautiful ants, and pretty slow to develop, i have a polygyn colony (2 queens) and only 6 workers in 12 months, I'm expecting to have about 15-20 workers by the end of summer, and next year around 30-40, they are a pretty big species, the early workers (first generation are always allot smaller than subsequent generations) are about 1.2cm, the queens are very big, about 2.2cm, they have very formidable majors, that can be close to the size of queens, but these wont appear until the 3rd year i expect. Egg to Worker development is slow, around 12-18months, but they lay lots of eggs

my brood after 1 year is (estimate) about 20 eggs & 20 larva, and some coccons, I'm expecting more eggs to be laid of course this summer, but bearing in mind that first gen workers only live for about 18months, i dont expect them to be around next year
max colony size for C herc is around 6 thousand ants, which would easily fit in a 1mx1m tank, but that takes 5-10 years, and allot of food!
