make them feel safe, helps to have a nem to have as a host. feed them 3 to 4 times a day and keep the temp around 82. female should be atleast twice the size of the male. i never seen a pair lay that the female wasnt alot bigger than the male. femals usually lays eggs around 2 years of age, possibly later. rule of thumb 2" or 2 years old. mose likely is 3" or 3 years old.
these are the basic frst steps that you can do. the rest is up to them. all you can do is make them feel safe, feed them alot and play some barry white!
