Are My New Danios Fighting Or Just Courting?

[Ilya]

I finally (by luck) got 2 male zebra danios and added them into my group of 4 female danios. I want them to spawn, however, just 30-45 minutes after I added the males, I see one pinning a female down in my java moss plant/ball thing. Are they just aggressive, or are they courting.

Besides, my females look pretty fat. D:

Not 100% sure - but mine do chase the females around a fair bit, not to that extent but they do....
My females been fat for ages...never had babies though.
