This is very vague in my memory, but I remember a few years back someone telling me that no one breeds Tetras in the US. I scratched my head on that statement but I remember searching for homebred Tetras and didn't get a single hit.
I went no further in to that as I didn't have any interest in breeding them, only raising them. That is around the time that I bought 100 chili rasboras. I hope you are successful! If you are, you should log it
