My black moor is chasing my oranda around. We noticed it last night and he's still at it. It is the classic breeding behavior. My ? is how long will it take them to finish? Is it long enough that I should separate them some or if I leave them alone will they be done faster? I can see the protrusion a little now on Thunder (always figured she was a boy) that people have said you could see if they are female. How do you know if your fish will even have eggs? Thanks for any help. I hope these ?s make sense. This is my first experience with this.
