The Development of Andinoacara Rivulatus (white & gold saum)

[MrsE88]

Mine are just coloring up more on their seams. Some look orange and others more like pale yellow. No outright whites that I can see:/

Yes, I definitely see some yellow and then others that start orange by the head then fade out to a yellow as you move towards the tail. I'm holding on to at least a few males (if I guess correctly) just to see how they turn out as adults. Would be kinda cool to have a tank with large males all with different color seams.

And if by chance I keep one that turns out female it would be interesting to see what a spawn would look like between them. Guessing it would remain a yellow color for them as well. Looking like you may need two whites in order to produce more whites.

 

[MrsE88]

Same here. Orange on the top dorsal fin that fades out to very pale yellow. Maybe it will be a fade to white as they grow? I too want to keep a couple and see how they turn out. I already have my eye on a couple of them.

Maybe we can figure out a swap once we see how they look to breed them to each other. Would be better than breeding the siblings to each other.

i can send a few and they can have a 10-way

So here are 3 that have been in my main tank somewhere around 6 mos old and 3 or so inches long. Any guesses on sex? I think dominant male; sub male; then female. But I'm wrong more than I'm right when sexing young terrors.

Still no white seams?

How sure are you on gender? I only ask because I am terrible at figuring that out. I have a fish that i thought for sure was a male due to color in fins but after a year now of growing out is what I am pretty sure is a female.

I agree that top and middle pics above look male and bottom pic looks female, but ive been wrong

Same fish

Not a single white seam as far as I can tell. And I'd say its 50-50 that I sexed each fish correctly .
