I have 2 sulcata tortoises. One of them is 8 months old, the other is 2 months old. My worry is that they are the same size. They live in a 90 gal aquarium, with a 160w powersun bulb. They eat lot of different types of veggies such as: romaine lettuce, collared greens, mustard greens, kale, and as much timothy hay as they can eat. They both get soaked once a week, and eat a lot. Can anyone figure out why they are the same size? Why the 8 month old isn't growing?
