The first clue that you know they are fighting is when you fid one of them torn to pieces. Even if you find one of them injured, you will not have enough time to get the enclosure enlarged and divided before the weaker one gets killed. And, if you are lucky enough to get them apart before one is killed, the vet bill to hopefully let the injured one recovered will be MUCH more expensive them making them seperate homes now.thanks for every ones concerns, but my mother says when they start to fight then move them, i think that is a stupid way of doing things. I cant do anything because my mom thinks she knows more than i do because she is the parent.
Not only am I a parent, but a grandparent and a great-grandparent. Plus I have over 15 years experience with 3 tortoises. They appeared to be "friends", but were really exhibiting aggressive behavior. Then one day, it went from aggressive behavior to brutal. About then I found TFO, and learned all of the things I was doing wrong. Hopefully our Mom will let you do what you have learned is right, and really, what can it hurt? Choosing to ot believe the advise from experts can hurt a lot, and by then it is too late, and impossible to make things better with "I'm sorry".
Good luck, and just keep trying.
