A 10 gallon would probably work for a 1.1 pair of auratus. But if you have any bigger tanks, I would suggest them. I have my breeding azureus in a 20 gallon long, and they still seem a little cramped for space. I know it is a hard comparison, since azureus are bigger frogs, and I have a lot of plant cover in my 20 gallon long. So basically, your 10 gallon will work, but I would suggest a bigger tank if possible.
