My marble angelfish laid eggs this afternoon, but the albino angle (which I think is male) didn't have the papilla shown, and didn't fertilize the eggs.
This was the first spawn. Neither one of them eat the eggs, the mother did a very good job in taking care of the eggs, she swam around the eggs to make good water circulation, but the male angel really didn't do nothing at all...
I haven't seen this two angels locking jaws, but I did notice that they fight against other angels, so I put all other angels to another tank and left them two at where they were at.
I don't really know if the albino is male...
Marble didn't attack albino at all, and albino was so free to swim around the eggs.
Does this mean Albino is male, just he's not ready to fertilize yet?
This was my first experience with fish spawning...but ended up with this sad story...
Looking at the female trying her best to make water circulation for the eggs, but at the same time I know the eggs are not gonna hatch...
What can I do to prevent next happening like this?

Please help...
