Chinchillas get along but mount?

[kdiz123]

Hi!
A few weeks ago I introduced my male chinchilla to my new male chinchilla. They get along perfect, no fighting, just that both of them will sometimes mount the other chin, but not especifically one but both of them tey to mount the other. Otherwise they get along great is this because they are still getting to know eachother or should i be worried?
Thanks

The mounting is a behavior to establish dominance. It is normal in the beginning of a chin intro but something to keep an eye on if it persists, because it can escalate to fighting. Make sure they are not biting or pulling fur because if this occurs, you will need to separate.
