Hi!
Originally I kept all of them together in a rather big glass terrarium (100X50X50 cm)
After some time I noticed that some aggression was going on among them.
At first I thought the male was aggressive towards females, but later I found one of the females was terrorizing the others.
(There are plenty of hidding places in the terrarium.)
I removed two females to smaller terrariums (40X40X40 cm) and now I keep every female separately.
Unfortunately before I did that, one of them dropped the original tail due to the bites from the aggressive female.
This year I had to remove the male as well, because she bit him on the head quite bad. He's OK now, but still has a scar.
I circulated him with all three females this year.
The interesting thing is, that the aggressive female laid three pairs of fertile eggs this year, while only one of the other two females produced a single fertile egg, which already hatched. All other eggs were soft and infertile.
Terrariums are furnished with a lot of tunnel-shapped cork bark pieces (providing plenty of hidding places), a bigger clay hidding place, some cork branches for climbing and at least one live plant (keeping humidity levels higher). Substrate is common peat, of which one third of the surface is moist, the other part dry. I spray every evening.
The substrate gets saturated with water after some time and needs complete change from time to time.
I keep them on lower shelves in my reptile room, with no additional heating.
The temperatures are 20 - 22 C by night, 23 - 25 C by day.
(The eggs are incubated at the same temp. range and take about 4.5 months to hatch. They are quite big and look almost identical to the U. henkeli eggs.)
For lighting I use full spectrum flourescent tubes although they never come outside during the day.
Light is turned on for about 12 hours during summer and about 10 hours during winter.
There's also a water dish and small dish with calcium (cuttlefish bone) for females. They eat quite a lot of it during breeding season.
I feed them mostly dusted crickets (Gryllus assimilis) and from time to time they will take small roaches (Blaptica) from forceps.
I also give them (specially females) extra vitamins and calcium diluted in water by the pipette.
For terrarium plants I use smooth-leaved bromelias or small Ficus trees (for babies).
My P. masobe babies spend almost entire nights up among the branches of these miniature trees.
But the trees need a lot of careful prunning to keep them in shape for small terrariums.
I find these small-leaved Ficus trees very useful for many climbing, humidity-loving geckos, such as Uroplatus guentheri (babies and adults), U. phantasticus (babies and adults), U. henkeli (babies), Paroedura masobe (babies) and A. felinus.
The small leaves create a great humid microhabitat, that holds humidity very well when sprayed with water.
I hope this helps.
I will definitely keep all the hatchlings from this year. Maybe I will sell some next year. It depends on how many there will be.
I will let you know, but if you are from the US, there might be a small problem of Atlantic Ocean to deal with.
Otherwise I'm at the Hamm expo in Germany in March and September every year.
