New to this and got a late start I have 2 large females 1 that I put with a norm. male and the other I put with a pastel male I never saw them couple but now after about 3 weeks they have gotten darker wont eat both just shed and very moody when I open their cages is it possible they are gravid or is this just me getting my hopes up they have been getting bigger in their mid area is there something else I can do or is it just a sit and wait game?
