Yay, a new breeding forum!
Here is link to a Banggai breeding article:

Update on one of my pairs:
I usually strip the eggs from the father around 19 days. This is really because I forget to keep accurate track of when I notice the fat mouth. This time, I noticed (it was my birthday actually) and I went to strip at 22 days and instead of eggs I got swimming fry. So much easier to deal with than eggs in a tumbler!
My male doesn't keep the eggs more than 3 days. He's nice and fat but for some reason he start eating again after 3 days. After I move, I will look for another male.
They have a nice big mated pair of PJ cardinals at Aquarium Concepts if anybody is looking for some. $99 dollars for the pair was the price I saw when I went there today.
Not sure this has anything to do with Banggais...

I'll prolly just be giving these away. Although they may all go to work.
Community tank? You could also try to isolate him right after you notice his fat mouth.
Yeah it is. Can I put him in a breeder net in the same tank? That might be a bit small
. Will 10G tank work?
A 10 would work fine. How many time has he held eggs? Sometimes the need several tries before they get it.
Many times.. I bought them from another reefers. They got frys in their overflow all the time. They were in a 180G though.
Since I got them, they breeded about 3-4 times but the male start eating after 1-3 days. 
I will try to setup a 10G tank after I move.
Thanks Rich!
Hi Rich,
What do you feed the fry? Will they eat flake? The male is holding the eggs more than 14 days now. Hopefully I will get some babies this time ..
Thanks!
Are the fry going to be for sale when they are big enough to not get eaten? I've been looking for two small Banggais to put in my 34g with my two black clowns...
