24" Pair of Silver Arowanas

Let me ask again.....

How do you sex, Silver Aros?

You really can't visually sex silver arowanas, we named them thinking the were both males Big Al" and "Hughie". I would suspect that they are probably M & F though. There are some physical characteristics that differ between the two the larger(top in pic below) has a broder jaw which is at less of an angle, body is not as tall, more slender and the lower fins extend farther back. The smaller's jaw is at a sharper angle and seems smaller in proportion, it's body has more girth from top to bottom and the lower fins are much shorter. I don't know if any of these characteristics are identifyinf M or F, these are just differences that I can see.

That was my thinking, maybe the future will hold proof.

males have a larger jaw and it protrudes above the nose...the females jaw is even or just shy of the nose....

I had heard this before, but was under the impression that this is not 100% proof positive.

Does this method of sexing apply to black aros also?
