Male or female? Jaguar, Argentae & bocourti

[Tylerjw]

Hey guys I’m having trouble trying to id the sex of this Jaguar about 3in and this Argentae about 2inch and bocourti 2.5inch

 

[duanes]

They are all just babies, so too young to get gender IDs.
None have had time to develop outward sexual characteristics.
With argentea, I have found they start to show about 7"
Below a male, note the head shape, lack of melanin markings, and pointed fin trailers.

Below a female, note the gentle slope of the head, and more dark markings

With bocourti, differences may not show until even larger. The one below is only about 10" and still isn't obvious.
It isn't until around 2- 3 years of age (the normal age of maturity) when males get a slight hump.

I'll let other post differences in managuense.

Managuense needs to be around 5-6” for better ideas on sexing. If it is sub dominant to the other 2, chances are that it may display female coloring

 

[newworld]

Yes around that size managuense can have sexable coloration but can spawn at much smaller sizes such as around 4”….

Male or female Jaguar please help!!!

Just like in your other post, it looks more like a male jag due to the dark spots in the lower half.
