Need help introducing my female Red Devil to my Flowerhorn

I need help introducing my 8 inch male Flowerhorn to 5 inch Red Devil. I tried and he started chasing her around so I separated them. Is this normal behavior?

I would like to try again tonight and give them a longer go, this time around. At what point should I separate them. My flower horn is my prize, I just got the RD last week.

Or I was thinking about keep them partitioned until I see eggs and them maybe separate them at that time? What should I do?

Anyone?

Why not?

I use a divider with a hole big enough for the female to get back
To her side for safety. Always works for me.

Did they eventually breed?

what size is ure tank man? if ure not confident, just would let them be separated... 8" and 5" is quiet apart for them to be together and even more risky if u want to mix it with one bull fh haha and plus, as they say, can prbbly be a breeding pair.. good luck btw, show us some pics.. we would be glad to see the both of them

The tank is a 75 Gallon. He's probably 7" btw. I always tell people 8 when I'm bragging about him, but hes probably 6 3/4 or 7. I cut a hole in the partition only big enough for the female to go through and she hangs out by the hole. She goes half way through at the most, but when he comes toward her she goes back to her side. I placed a clay pot on his side. Not an actual pot but the flat plate shaped piece that go under the clay flower pots to catch the water. His male part is sticking out and his red is a little more intense than usual. I'll post a pick today after I finish cleaning up the tank.
