yeah, my female has never showed anything like the first picture ever! but she shows many other signs, aggression, not eating much but now she actually is. any other signs? could she show delayed colors? she hasn't showed yellow and the blackish brown with speckling blue. she has the blues.if they are mated they should show those dark colors while the male is still around and the two are still in the same cage...however some of them won't keep the dark background color the whole time they are gravid. They will if they are stressed.
