help

I have two male chinchillas and i am a bit concerned with the noises they make at night. Ive had my guys for a while now and they have been with each other since they left their mom. They get along usually, but latley me and my boyfriend have woken up to some noises. Sounds like theyre fighting, it just sounds like a bunch of commotion (becuase theyre usually in their house) Im not sure what to do, I havent experienced this before and i dont want anyone getting hurt. <aybe I should seperate them? help
