I'm an anxious mom, I offer food and water every other day to all, boys and girls. I feed the gravid females enough to keep them healthy but definitely agree with Rebecca, I don't let them stuff themselves. I water everyone with a syringe and use glaceau water, it has electrolytes and feeding/watering them individually I can keep track of how everyone is doing. Yeah, I'm crazy but I'm happy ^.*
As Digger said.... Water, water, water. SO important. I pretty much feed according to what the mantis likes, their size.. Their health status and age. Elderly and handicapped or infirm get a lot of soft crix and waxworms. Everyone gets a variety of mealworms, waxworms, superworms, crix or either dubia/lobster. I am leaning toward ditching my dubias as far as feeding and going with lobster roaches.
