Cyclosternum fasciatum breed report

very successfull

Female: 3 years old 9cm, legspan, setup in a sq tank 25cmx25cm!
mated: with two dif males 3 weeks apart! after 10 weeks from first mate i noticed female earthmoving! she had fattened up nicely! I then put a sq container in the one corner with some substrate in it! She then dug a hole next to container and covered herself in it! 2 days later i cut a small hole throug the webbing and saw her holding onto the sack!
I took the egg away 28 days later! I then opened the sack, they were eggs with legs! they then molted again 3 days later! they then molted into full spiders 10 days after that,
Total days from day egg was made to being fuul spiders--43 days!
I then separated them ---760 perfect spiders & 10 never molted properly!
Babies were between 0.7 & 1 cm in size!

I have also bread another smaller younger female (also mated with one of the males from above breed!) very similare prosess, she laid in the container i gave here though! times were very much the same, --420 babies!

Hope this might help sum1! if you want any other details like heat & water etc.. please drop me a msg!
