In fact, there is 1 more question for Blue Sir,

If I keep my ph at stable 5.8, does it affect the hatch ratio of the eggs?? I do so, becos I don't want it to burn its tail fin and for convenience, anyway, should I lower the ph level after the parents laid eggs in order to increase the hatch ratio, or should I just leave it the way it is?

pH ~ 5.8, soft water, and temperature at 26-29C, are very very nice for hatching eliza's eggs.

If you increase pH: You will tend to get more male.
If you increase temperature: You will get more male.
BUT there are limits of course... if pH is too high, you will have more abnormal fry; if temperature is too high (e.g., 35C), many fry will not go out (hatching rate problem) ...

I see, then I am doing fine, but wonder why the 1st and 2nd birth only have like total 10pcs hatched..... anyway, thank you.

Another thing: The amount of ammonia and NO3 in water... if the level of these toxic things is high, hatching rate will also be lower...

I change 1/3 water twice a week..... No3 level is always below 5mg/L..... but when they have eggs... no change.... NO3 is between 5-10mg/L... maybe this is the cause!
