Babies:

Housing:
A baby Aldabra tortoise will require a smaller enclosure at first but will need to be upgraded as it grows. A minimum of 4×2 feet is recommended for a baby, with room to expand as the tortoise grows.
Use a mix of soil and sand or coconut coir to maintain moisture. The substrate should be kept slightly damp but not waterlogged. Provide hiding spots and shelters where the baby can retreat to feel secure. Use materials that are easy for the baby to navigate. Provide space for the baby tortoise to move around and explore. Include safe, non-toxic plants, rocks, and logs for enrichment. Keep a heating lamp for warmth.
Maintain a temperature range of 80-85°F in the enclosure. A basking spot should be provided with temperatures around 90-95°F. Allow nighttime temperatures to drop to around 70-75°F.
Get a UVB light source for 10-12 hours daily. UVB light is essential for calcium metabolism and overall health. Replace the bulb every 6-12 months as its effectiveness wears off.
If the weather allows, supervised outdoor time can provide natural sunlight and additional space for exercise.
Diet:
Offer a variety of leafy greens such as dandelion greens, collard greens, and mustard greens. These should make up the majority of the diet. Dust the food with calcium once in a while. Ensure a shallow water dish is available at all times. Baby tortoises may also like occasional soaking in lukewarm water for hydration.
Maintenance:
Clean the, enclosure daily and replace soil every once in a while.
Adults:

Housing:
Aldabra tortoises require a large enclosure due to their size. For adults, a minimum of 1,000 square feet is recommended, but larger is better. Outdoor enclosures are the only option because of their size.
Use sturdy, high fencing to prevent escape, as Aldabra tortoises are strong and can dig. Ensure the fence extends underground to prevent digging out. Use a mixture of soil, sand, and organic materials that allow burrowing and helps keep the humidity. Provide shelters and shaded areas where the tortoise can escape the sun and weather. At night, temperatures can drop to around 70-75°F. Keep a shed or doghouse for them to sleep in when it’s cold.
Diet:
Aldabra tortoises are herbivores. Their diet should consist mainly of leafy greens (like dandelion greens, collard greens, and mustard greens), hay, and a variety of fibrous vegetables (such as squash and carrots). Offer fruits sparingly as a treat. Suitable fruits include papaya, mango, and berries. Give them calcium.
Maintenance:
Clean their enclosure and take out any leftover food.
Size:
An Aldabra tortoise can get 550 pounds and four feet long. They are also very heavy and could destroy furniture. With an animal that big it is best to check if it is legal to own one in your state.
