Silver and black Arows breeding?

Just because they haven't done it doesn't make it not possible. I'm sure there's plenty of other possible-but-too-boring/pointless hybrids that could be created but haven't.

arowfan; by all means ask, its started an interesting discussion. I'm just saying that IMO the fish are so similar that there is nothing to be gained by crossing them.

IMO if it were possible to make fry more rigoruos, unlike that of black aro aspring, and still as colorful and no drop eye, this could be a plus to the hobby/trade.

That depends on your motive for keeping the fish, I'm not big on hybrids and never will be. Yes you could probably make it bigger/stronger/better/whatever but it wouldn't be a species any more.
 
i know hybrids arent that cool

But the resulting offspring would be mules, infirtile hybrids. The Species are the same but the Sub Species are different.

Not all hybrids are infertile. There are many examples of hybrid propagation.

I can see a slight benefit long term in this situation. There is the chance to breed out the drop-eye gene by giving it Black Arowana Ancestry as well. It would take some time, but my guess it your fry would consist of some baby Silvers and some baby Blacks, with slightly different genes. Theoretically, and mathematically, 1/4 of those Silvers should lose the drop eye gene, and 1/4 of the Blacks should gain it.

Continue cross breeding the Black and Silver over time and weed out their baby silvers that don't end up having drop eye.

Start breeding those Silver without the gene and you should have a nice selling point.

This is strictly theory and may not work. The Silvers gene could be completely dominant and cross breeding a pair of a Silver and Black may only produce silvers, or vice versa if the Blacks genes are completely dominant.

There is a lot more to it than this. You may have to fool with Silver Male and Black Female, or Black Male and Silver Female. I don't know if the drop eye is a recessive gene or a dominant one. If it's a dominant gene it will be real hard to cross breed it out, and may not be possible at all. If it's recessive, cross breeding could eliminate it from some Silvers.

There is also the possibility, and it is pretty common in cross breeding in all kingdoms and species of animals, that the Arowana Fry could end up sterile.

Genetics is a bit more complicated than this.
 
i think he meant that
 
haha sumtimes that can be confusing subspecies,species,genus,family etc
 
Not really, the only thing that makes it confusing is that the majority of people don't bother to learn anything about Latin nomenclature, or even the names of the fish they keep.
I don't mean to be a picky b@stard, but I hate seeing people use the word "species incorrectly. (or even worse saying "specie"!)
