Do the females tend to be more peaceful

Here are photos of the other two Do you think that they are also thick lipped rather than honey gourami? Any idea if they are male or female

the other 2 are smaller, how can you tell the difference

Here are a few photos

I have 3 honey gouramis & 8 harlequIn Rasboras in a 20 gallon planted tank. The largest gourami has become quite aggressive and territorial. Chasing the other fish. I don’t see any eggs or nests. Any ideas how to deal with this?
