White Saum gender??

[tpaquarist17]

Hey guys and gals, I’ve had this pair of Adinoacara Rivulatus for a couple months now. Both of which are colored differently and vary in body shape but I am not yet seeing any tell tale signs of sexual dimorphism yet. One seems to have a thicker white line on the dorsal and caudal fin. That same one also is getting a more pointed tip on its dorsal. My guess is that both are female and one is showing more “male” dominant traits since it is the dominant fish out of the two. I’d just like to hear your thoughts and opinions!! Thanks!

p.s. they just had a big meal hence the big bellies and the water isn’t crystal clear because of a water change an hour or so ago.

I would say both are female.

In males the bright shiny green on the body continues into the dorsal tail and anal fin.



In females the green is not in the fins.

Yes it's a orange saum, still the same fish. See this female has no green in the dorsal tail anal fins

Jexnell yeah, I was afraid they both were, they’re still fairly young but I figured if one was a male you would be able to determine by now

Also note the dramatic slope of the head in Jexnell's pic, compared to the gentle slope in opening posters pics
Below is a close cousin Andinoacara coerleopunctatus, gender traits are very similar throughout the genus.
First a female.

Compare head profile with a male of the same species.

another angle of a male, and how the blue is more linear in the anal fin.

duanes this is a previous male blue acara of mine, I just didn’t know if since they are young if they are dimorphic yet or not

Yep this looks male to me. The slope of the head, the linear color in the anal fin, and (although not always the case) the pointed fin tips of the dorsal and anal fins.
These smaller Andinoacara (like pulcher, coerleopunctatus, or bloombergi) mature very quickly.
My currently spawning female coerleopunctatus are only @ 3", and first spawned (albeit unsuccessfully) last breeding season at only 2"
