you need to give more info on the situation. any thing you can think of will generate a better response from the site...cage temps,.. how long they have been together,..what behaviour is she displaying,..is the other one eating,..has she lost or gained weight,.. does she look like shes going on shed,..etc etc, keep in mind though it is mating time for diamonds still, and just because you havent seen them mating is no guarentee that they havent unless you watch them 24/7.
