I'm starting to worry about my star tort, Ravi. When I bought him, from someone here on the forum, they told me he was a little over a year old. But, he still looked about hatchling size to me. I've had him for two months now, he eats well, (spring mix, catus, Mazouri, etc...) and gets sunlight every day along with occasional calcium and vitamins. Still, he is only two inches and weighs 1.1 ounces = 31.2 grams. Are they really slow growers? Could something else be an issue?
