identifying the sex of Electric Blue Acaras!!

[fishfam1]

i’ve got two eba and i purchased them from my lfs within two weeks of each other and i want to say one is male and one is female but i just don’t know.. can anyone help me out. i’m gonna post foir different pictures if you look in the top left corner i’ve marked two with an S and that’s the one i believe is male and then i marked the other two with an X and i believe that one is a female then i posted one more picture of them next to each other and also labeled them so you can tell them apart but i want some other opinion.

They both will have pointy dorsal fins. The male dorsal fin will extend greatly back over the tail fin, almost like a convict.
I would be safe to say the one you marked with an S is male. The female will have a pointy dorsal fin as well but more rounded and much less extension. So X could be a female or late bloomer. I would lean on female even though it can get difficult like sexing EBJD's.

I personally couldn't tell the difference until they spawned. You can vent them also to see what sex they are.

how do you vent them? tlindsey

They are not out all the time, but when they do drop down the Male as viewed from the side looks like a V

Females tube is blunt on the end looks more like a U

random but you guys ever heard of the twig catfish?

Google the genus Farlowella to get info on twig catfish.
I find many species of the genus Andinoacara both males and females have very similar fin ends (rivulatus and stalsbergi the exception)
Below a wild caught female Andinoacara coerleopunctatus (close cousin to your EB Acara)

Now a wild caught male

With line bred fish like EBs sometimes normal gender differences get blurred, in the selective breeding process (at least for me)
