I have never had notherns, but I do have Texas gators. They need to be fed pinhead crickets. I use crushed one-a-day vitamins as a suppliment. They need a small water dish and one side of the cage that it moist (not wet). They should do fine. One of my gators will be laying her eggs next year so I wil be where you are. Good luck!
