I just noticed there's 3 Banggais holding at this moment .
In a way I regret getting the original couple a few years ago and the reason is precisely this: they breed and release a small group of baby pandas in the tank, and they're the cutest baby fish ever... and it's tough.
Other than that they're fascinating fish. The dynamics of the group is really complex.
The reason there's 3 males holding at this moment is because the mother of them all got her male pregnant, kicked him out and he had the babies on his own.
In the meantime she seduced one of her sons (a widow, whose wife she killed, I believe), got him pregnant, than she took her original husband back and got him pregnant.
Just by coincidence, one of the young males is also pregnant from his sister.
