Why are my angelfish eggs dying?

[bettaobsession]

Sorry it took me so long to get back to you, but the question i heard most was are you sure you have a true pair?
Yes very sure, i am positive i have a male and a female but im not sure if maybe one of them is unfertile.
Sometimes the male like hardly does anything just sort of fertilyzes in the wrong place or just watches.
The tank has been set up since like march, i didnt think that .25 was much ammonia.

you confirmed by verifying the Ovipositor?


are these angels young?

how often have the spawned?

anything over 0 NH3 is a slight concern.
but the test kits also measure NH4.

is the Ammonia test done after water change? if so how long after water change?

Are the eggs white/opaque or clear after spawning?
