Beautiful fish! I have some from Rapps and I love them. If you put them under a blue actinic light w/ black sand they look incredible. I moved mine to an aquarium w/ white sand and lights to bring out reds and yellows in fish and they look faded out now.
I've found that the size difference b/w male and female is greater than in a regular convict. And if you put them in a tank by themselves to keep the spawn, the male can really wear her out. They are not as bad as Sajicas, where the male wants it when he wants it, but pretty close. Be careful if they are alone as I currently have my best female recovering in another tank.
