Back in the day Ginny Eckstein was my mentor/adopted mom....she had two blue eyes (male and female). She kept them grid divided as they are quite intolerant of one another. One day she removed the divider and all seemed to be going very well. She went out for a bit and upon her arrival home the male had basically descaled (if they had scales) the female. She was dead hours later. Before disposing of the body she sliced open the female to find her with many eggs. This is the closest thing that I have heard of.
Back in the mid 80's I managed a wholesale tropical fish operation in the Northeast. We would get blue eyes in every week. Not just blue eyes....but nice blue eyes with caudal extensions....not to the level of an adonis, but some a couple of inches long. The extensions would take on a light yellowish color to them.
Of late I've become kind of obsessed with this fish. Earlier this week I came across a post on another site of someone outside of the US who was expecting 7-8 pieces soon. They're coming from somewhere....and I don't think it's grow outs from breeding! My guess and hope is that we have not seen the last of them, although we could be waiting for quite some time.
