Hi I have a female redfoot tortoise 6 inches or less long. I want to buy a new redfoot tortoise that I already saw at the store. Its a female and its a 4 to 5 inches baby redfoot tortoise. Ive had my redfoot for 2 years and I am buying a new crate (cage etc.) I want to know if they will fight or the old one will kill the new one. Remember both are females. Please help and thank you.
