She looks fantastic! You should definitely think about breeding in the future... I'd love to see more of these in hobby! I can never get enough of annulateds ever since seeing them in Costa Rica years ago - they are just something special imo.
At that size, a small meal every 5 days will work best to keep a steady growth until she is another year or so bigger and then spread out the meals.
Best of luck with her and be sure to keep photo updates coming!
