I know this question has been asked before but...

[JOEG.]

does anyone here know how to definitively tell the difference between a male and female silver arowana??

 

[DeLgAdO]

not possible

both male and female share the same characteristics (for example it is said that males have a bigger jaw to hold the babys, but females can have this characteristic as well)

 

[WyldFya]

Sure you can tell Del. Generally the one laying the eggs is the female.

What? You should know that one better than most. Unless that is a little boy you have laying the eggs...

AGREED

 

[JOEG.]

what physical characteristics definitively define a male silver arowana from a female silver arowana before she lays eggs>?

 

[WyldFya]

No physical trait is exclusive on silver aros, other then the egg laying thing. Everything else can occur in both males and females.
