Hi all, I have a 55 gallon feeding trough that is about 15-20 square feet (+ about 5 inch deep substrate) where I keep my russian tortoises. I currently have a 5.5” female and a 4.5” male in the enclosure. While my male has not shown any excessive breeding aggression besides the mating that occurs probably once a fortnight, I’m getting worried after reading all the stories about suddenly really aggressive males harassing one female because they didn’t have any others to choose from. Is the enclosure big enough to add another female? They have more than enough basking space and hides, and getting more food is not an issue for me.
