I have two male chinchillas, a five year old and a six year old. I recently adopted them as a bonded pair and was told they had never fought before. They have gotten along fine and have acted like brothers until just now. They fought over the food bowl and started barking and making loud noises as well as wrestling, sort of. I opened the cage and they stopped but then started again. For tonight I separated the two levels so one is on the top and the other the bottom, both with food and water. I don't want to have to keep doing this because they normally get along well, but I'm scared to put them back together. What should I do? I'm new to owning chinchillas and I don't know what to do or how to handle this!! Thanks!
