Good questions. Great you ask! Now I am going to explain very carefully. You like it or not, it is up to everyone decision.Hehehe I finally make this decision after I have four males been through like this, and many big healthy babies. Here I would like to share this to everyone.
Firstly, do you know babies need immune system for their bodies to defence? Just like a baby need their real mother's milk and not power milk. This is the way betta father can feed his babies with his mucus (saliva). This is how in the wild the babies are broad up and become strong and reproduce again. I have seen my male bettas doing this in all 10 days.
I can see the male is teaching the babies not sitting at the bottom of the tank too. He keep diving to the bottom, gulping the babies and then release out the babies on the water surface. He even making the babies swim up to the surface of the water. I realized mostly the babies are on the top and middle tank now.
Now I am talking about the reproduce. I am pretty up-set because I bought quite a numbers of bettas and they don't know how to breed right or totally don't know how to breed at all! I think some of you have the same problems. I have more than 2 dozens males and females (30 counted) import from thailand or from USA thats don't know how to breed. Why? Think about the raising by human Salmon fish. They don't know how to reproduction even the ocean turtle that raise by human. They can't even survive back into the ocean. In my opinion, they took the male out too fast.
As for how many babies been eaten? In my opinion, I see many (too many) big babies swimming healthy everytime. My last batch, I got 250 more babies from my red halfmoon. I took out the father in 10 days. He is the first time breeding too.
One last thing to add in my final thought from my observation. The father seems happier after taken him out. When you put next to another female, he flare like crazy and wants to mate! Not like taken out the father after 2 days babies hatching. They look so sad and depress like want to dead. It is up to you now members.
If you want to tried my method, you have to trust your male betta. You can using a petmart female and breed to do the experiment and see for yourself.
