Well, what kind of anuran is it? The exact species, plus the subspecies? Most anurans from the south do not need extensive hibernation. If you have a wood frog, northern leopard frog, toad, etc, then consider it. Hibernation is a difficult process. Its best done outside so the frog can do it itself.
Its difficult to tell when your frog wants to hibernate. The only true way you can tell if you have been "cycling" the animal. They should stop eating.
Basically, you have a timer on your aquarium. Set the photoperiod at 14 hours a day in the summer and 8 hours a day in the winter. Make sure its cooler in the winter, you may want to move him / her tank to the basement or in a cool garage for a few weeks. Do not feed. That is the best I can tell you. You can also let it go if you have a garden pond outside.
