I read that article years ago, and took the practice of leaving the male in with the fry. While it is true that there are instances of "bad fathers", I sometimes wonder how many times this is once again our misinterpretation of what is truly going on. I have one example. I had a beautiful Double ray platinum male. Simply gorgeous! I mated him with another platinum female, and he ate the eggs. I blamed it on him being young and inexperienced. I tried him again. Again, he ate the eggs. So I wondered if maybe there was something wrong with the eggs, so bought another female. Spawned them, he ate the eggs! DANG! such a beautiful fish, and he is an egg eater! about six months go by, and at a fish club meeting, while talking about this, I happen to find out the two females were actually cousins. On a hunch, I bought another female, and had total success! I even left him in with the fry. So sometimes when we "think" their is something wrong, what is really "wrong" is our interpretation of the animals behavior. I loved Halo, may he rip. He taught me soo much and was one of my best fathers.
