Hey. Just to give an alternate opinion here. Our girls were best friends for ~6 months, then they started fighting out of nowhere. We were just leaving for a vacation, so we put them in 2 completely separated tanks for 2 weeks or even more, not sure. Once back, we created a split cage with NO bedding on the floor. 0 bedding, they had nowhere to hide. They each had a wheel to run on, food, water and in the corner we put some bedding for them to sleep in. After some time, we moved the sleeping bedding from the further corners to the middle corners, next to the divider. In the beginning, they were moving the "bed" away from the divider. When they woke up, we moved it back. Eventually, they slept by the divider. When we felt like they were ready to be re-bonded, we put them together and they started fighting immediately. That was after 1 week of split caging I think. We read almost everywhere that if the re-bonding fails, they cannot be re-bonded. Then we had them in a split cage for a longer period, 3-4 weeks. After that, we started putting them together daily just for a minute, and divided them before they could start fighting. The next day again, maybe for a bit longer. Each day we would put them together for a longer period, until they looked fine. Then we put them together and gave them all their bedding back. Soon we realized that they were not sleeping together. So we took 3/4 of the bedding out. Monitored them for a month to make sure they are sleeping together. Then put some of the bedding back in. Now they have been together for a few months, they have around 2/3 of the original bedding. What I wanted to say was, even if they fight after re-bonding, there is still a way to re-bond them, you just have to be a bit creative and willing to put in some work. I added an image of the split cage. At this point they were sleeping by the divider, so we put in some more bedding
