There really isn't much difference in the care of gatlings, juveniles and adults. Due to their smaller size, you'll need to pay a little more attention to hydration and humidity with a baby. Daily soaks for little hatchings vs. once or twice a week for older larger tortoises.
I have two hatchlings and am curious. What do you mean daily soaks? Are you referring to salt baths?
Soaking is just letting a tortoise sit in warm water. This lets them to stay hydrated and drink freely. I prefer to use an opaque container that is stable, too deep to climb out of, and allows some movement. The water should be luke-warm to warm. Hatchlings can easily overheat so do not make the water hot. Make sure it’s deep enough to cover the lower 1/3rd to 1/2 of the shell. Or, fill it up to where the bottom half of the shell meets the top part. If your room is cool, you may need to put the soaking container halfway in shade and sun or in their enclosure. You could also replace the water when it gets cold. Use water that is safe for you to drink. Filtered tap water works fine.
What species? Tortoises should never live in pairs. They need separate enclosures. Groups can sometimes work, but not pairs.
I have a Nicharagian Ornate slider. His terrarium water is 82* F and under the heat lamp it’s 90 or more. How warm should the water be for the soak?
This thread is in the Russian tortoise section. We are talking about tortoises. There is no need to soak an aquatic turtle.
