I am new to the snake raising and was wondering what size of mice my rosy should eat? it is about 18 inches long. I usually feed it three pinkies but feel like I should try fuzzies. My kenyan sand boa is feeding on pinkies and doing well. The rosy lives in a 40 gallon breeder with three hides and a fake plant for it to climb on. The sand boa lives in a 20 gallon long with one hide and a small decoration. I bought the rosy almost a year ago and never had a problem with health or feedings. if you have any comments or suggestions feel free to ask! I can even post pictures sometime.
