Ficus are good but Pothos are better. Dwarf Umbrella trees are sweet too, I was never a fan of the ficus plant just because of the weak little branches that crowd up.
Are you asking how long does it take to emerge out of the egg once it is hatching? Or, incubating time?
Coming out of the egg once it begins it's journey can take up to a whole day and a half.
Incubation period depends on the temp. Anywhere from 5-14 months, only heard of one hatching clutch that was just at 5 months from my friend Pam, and only heard of a clutch hatching at a long 14 months a couple times.
I'd say the average time is around 8 months...
