Do you have more than one sulcata? They really need to be in separate enclosures. They don't need or want a friend. They see another tortoise as a threat. 10 gallons is too small. A kiddie pool is a great size but hard to cover and you will need to cover it to keep in the heat and humidity. Several people have made great enclosures with large plastic tubs. We have an enclosure section of the forum with lots of ideas. https://tortoiseforum.org/forums/tortoise-enclosures.7/My enclosure is extremely poor sadly. Its a 10 gallon tank temporarily. I dont know where to start for the new enclosure. Im thinking of getting a kiddie pool and putting them in there. Is there anything you could reccomend and a price range?
