the Amapa Tetra finally Spawned. The previous failure reason seemed ridiculous now.

Описание: After more than three months of multiple failures, I have finally obtained some Amapa tetra eggs.
The reason for the failures was ridiculous, just as I had expected before making the first attempt.
The breeding of Amapa tetras is actually as easy as breeding all my other common tetras.
What I did wrong was either not being able to sex them properly, or perhaps I just had the worst luck?
I had purchased those tetras twice, and all of them were female.
Although breeding them turned out to be very easy—as I didn't make any water adjustments like lowering the pH, softening it, or changing the temperature—it did take me more than three months and multiple times of failure.
However, it was not time spent in vain. It has somewhat motivated me to make small progress in my breeding projects.
At this point, it even makes me wonder if I had the same problem with my ruby tetra breeding failures. Are all my ruby tetras male?
I will surely make more attempts at my ruby tetra breeding projects.
