Juvenile Borellii “pantanal” sexing

[Andrew H]

Hi, these little guys are a few months old now and I’m hoping to separate the males and females… any help on the determination? I’ve got a few photos attached which ought to be numbered on the pic. 1-4 are the kids and 5 is the mom (who is suspiciously yellow).

More than the ID - can you tell me what features you’re assessing? I’m looking for a fishing pole vs fish here.

Thank you in advance!
Andrew

Just random guesses which can be safely ignored - first 3 males; 4th maybe male and 5th female.

Check out <this thread>. How big are they?

Will do. 2-3 cm range approx so maybe still too small…

Yep, definitely to small for safe sexing.
