I am glad my post was of help...... I would not advice you to put your "diabla" with a partner, for if she was raised by herself, and is agressive as you mention you might end up with no "diablos" in the end....
What I advice you to do is that, if you are interested in spawning cichlids and raising their fry as a pastime, start a new aquarium with five or six juveniles of an easier to breed CA species (convicts, firemouths, etc.) and become acquainted with their behaviour and needs before attempting to breed the larger more aggressive and difficult ones.
I believe that there are some very nice articles for beginners here in the CRC at a very reasonable cost that may be of help to you.
Good luck with your fish, and my best wishes for 2006!
