I've not got a big collection, just two males and three females. For the last couple months or so the males won't eat, and they keep dumping their water bowls. I've not started breeding them yet, planning on starting next fall. I keep them all in the same rack(different tubs of course). Temps and humidity are good. The females are all still eating good. They're both about 2 years old. Should I buy a different rack for the males? Just curious if this is natural this time of year?
