how long does it take a baby tortoise to grow
Rating Newest Oldest. Best Answer: well, depends. If you are taking about a baby red eared slider, they grow quickly for females, and slower for males. Females grow up to 10-12 inches, and should get to this size in about 5-10 years, and males grow to 8-10 inches and get there between 5-10 years as well.rowth is depended on enough calcium and vitamins in the diet, from the lighting, and also from the tank size. For example a turtle that is confined to a 50 gallon tank its whole life, will become stunted, and not grow as much as lets say a turtle in a 250+ gallon pond.
