Also be aware that hatchlings can deteriorate quickly. I lost my hatchling Hermann's recently, although I took him for his first vet visit within 2 weeks of receiving him, and although his symptoms were not indicative of anything other than a parasite infection (which he was treated for and a subsequent fecal was clear). His husbandry conditions were the same as my other Hermann's, who is thriving. He seemed more or less the same for a month, and then went downhill very rapidly, over about a 24 hour period. I've since been told that young hatchlings do sometimes just fail to thrive, and some just don't make it past 4 or 5 months, so you do need to be careful.
10 gallons is too small for even the tiniest tortoise. Go out a get at least a Rubbermaid blanket box--it's not huge, but it's a lot better than nothing, and you could get it set up tomorrow.
