I have 2 male rats, each a little over a month old.

Now I know that they're supposed to play fight a lot, but they seem to do it quite a bit...and I'm worried that it's not playing. One of them tackles the other and just kinda nibbles at him while holding him down. The one being held down squeaks sometimes, which makes me think he's in actual pain, and it's not just playing...

How do I know when it's play fighting and real fighting? If it's real fighting, anything I can do about it to get them to not do it so much?
