For a flowerhorn to die it will take longer than a day. I'm sure the female can handle herself. Let them mingle and if you see damages on any of the fish separate them and keep them separate until your ready to breed.

You've obviously never bred FH lol. The males can be very vicious and can kill a female fairly quick. A close eye is always needed when breeding
