You are right! The person that gave them to me gave me a big aquarium on pellets. She gave them to me right before they went into hibernation. I had already changed the pellets in the aquarium to dirt. I've moved recently and now have this wonderful spot on the side of my place that I can put them outside! I didn't realize that they needed to be soaked so much! I have them soaking right now!Hi, and welcome to the Forum!
Those two desert tortoises are in dire need of some water. Soak them for about a half hour daily for at least two weeks, then after that you can go to once a day for about 15 minutes. After a month or so if you see that they are getting into their waterer or drinking on their own, you can cut back on the soaking.
Whoever gave you those tortoises kept them way too dry. Baby tortoises hatch out and stay underground most of the time...underground where the earth is slightly moist. I'd be willing to bet the people you got those beautiful babies from kept them in an aquarium on alfalfa pellets. That's the old school way. We've come a long way since then, and the babies are very lucky to have been given to you, a person who is interested in knowing the best way to care for them.
Keep a close eye on them. Being raised dry like they were means it's quite possible they may have developed bladder stones (very common in dry-raised desert tortoises).
Here's a link to a good care sheet on desert tortoises (He's in Bakersfield, CA, but the care is the same for Arizona tortoises):
