Hello,
I need to know what the gender of my two Buenos Aires Tetras. Any helpful hints would...well be helpful.

edited due to content, sorry for any inconvenience

to be honest i dont think there is a way *shrugs*

I should imagine the female will be bulkier when they hit adulthood but i cant say for sure

Old topic but...

Females more fatter and larger then the males. Males tend to be really slender and more colorful.

It's really tricky with large bulky tetras like buenos aires ones.

:D
