huh, interesting-didn't know about the fatty deposits! i was def. thinking that the arows looking down for the food is what causes it...

Silver and black Arows breeding?
- Thread starter arowfan
- Start date
i agree
I have only known of Asian arowana breeding in home aquaria and very few at that, mostly they are all bred in ponds. All SA species of arowana that are bred are in ponds--never heard of any SA arows breeding in home aquariums.
Yes, wild silvers do get drop eye there is adocument on National Geographic on the Amazon and a part of it is on silvers and shows large adults schooling together in the river during lower water seasons to feed on smaller fish & they all have drop eye.
Possibilities and theories can be talked for infinity but we don't know until it is actually done.

There must be a big difference between those who grow in the wild than those who grew in captivity.

I agree, I haven't found any documented proof of "drop-eye." It seems it's all hear-say. If they get it in the wild as well, it could be from the same factors as being kept in captivity, or it could just end up being genetic.
Nothing prevents an Arowana from looking down in the wild, or from it eating fish that could be fatty in the wild, etc..
Perhaps the ones that would get it in the wild die young because they can't look up into the canopy of the flooded forest and therefor don't get as much food?

That has always some what been my veiw. After seeing the wid aro videos on youtube and seeing how my two silvers are handicapped by the DE. Also it is possible that aros in the wild are able to recover from slight cases of DE.
It is possible that the Black and the Silver could mate but improbable.
If one really wants to crossbreed Manually Augmented Spawning (hand stripping the roe and sperm) as is performed in fish hatcheries would be the best method to use.
But the resulting offspring would be mules, infirtile hybrids. The Species are the same but the Sub Species are different.
Also as Osteoglossidae are "mouth breeders" this would make the operation even more difficult, especially if manually spawning. Of course yolkers can taken from the male after they reach a half inch or so but do we know if male Aros give off some type of hormone or enzyme necessary to grow the fry? No.
All in all, while the crossing might provide a spectacular looking fish or an ugly as hell looking fish, it would be a one time deal as they wouldn't produce any offsring of their own.
