Very informative. The chasing behavior in the wild would most likely have resulted in chasing the more mature cannibalistic young fish out of the area of the smaller fry this way the father would have protected the smaller fish so they could grow. The cannibalism also weeds out the weaker fish. Just my thoughts I'm not an expert.
Thanks for your comment. My idea is the same. I was surprised that male parents never hurt a big child who was the culprit. I felt that the male parent felt that he was driving away his bad son with love as his child properly.
thanks so much, now i can see how the behaviour in nature or wild, the first who come out from their nest after the mating, is the mother, after her task finished and the possibility is she back to her territory or just keep enough distance. Then one by one the bigger fish come out, they become too aggressive and the father will always chasing them, also, they must be need more food from the father territory including their own bro and sist, till all the fry is gone, to start their own life and to get their own territory, but in fact, i'm sure the father, if he successfully catch the big daughter or son, he will bring them to the edge of his family territory, and maybe hope that child can find new land or disturb other competitor, just like the lion do. Your video recording give so much info and knowledge to my very little info about channidae, happy to see Your group success to breed this beautiful species, once again, thank You
