I apologize and try to translate but my english is not as good as my french : I'd observed a moreless similar behaviour with a female of Pseudocrinalibus philander ( a mouthbreeder ). I'd isolated a female with the eggs in heir mouth in a little tank; then the youngs appearred : nothing special.... After 4 or 5 days I put in this tank any live Artemias to give , in my mind,a good diet to the female. One days after the number of youngs had decreased, the day after : same thing and I observed that the female chase and eat young after young. Live artemia and loss of maternal instinct I don't know.
