So there is no chance of a black and a silver hybridizing. They look so much the same.

 

[Kamisan]

Silver arowana (Osteoglossum bicirrhosum) and Black arowana (Osteoglossum ferrerai) can be crossbred easily. It's pretty common here at my place.

Never seen proof of this could you possibly post some pics of the Osteoglossum hybrid?

For me it should be call as Crossbreed rather than Hybrid.

My understanding;
Osteoglossum A + Osteoglossum B = Crossbreed.
Osteoglossum family + Scleropages family = Hybrid

Will take some pictures of the Silver X Black crossbreed aros whenever I got the opportunity and surely will update here.

So then by your understanding there are no asian hybrids just crossbreeds?

In the cichlid world, Amphilophus trimaculatus(trimac) x Amphilophus labiatus(red devil) This would be considered a hybrid not sure why the same would not apply in the arowana world?

Yes there is no Asian arowana hybrid and since all Asian arowanas are under the same genus and species of Scleropages formosus (Schlegel & Müller, 1844), inter breeding them will not meet the hybridization criteria.

ok, so their arent hybrids but crosbreeds of arowansas thanks everyone.

Kamisan, you are on the right track, but not quite correct. have a read of this; http://en.wikipedia.org/wiki/Hybrid_(biology)

[I replaced Wiki's examples with more relevant fish examples] Quote;
In biology, hybrid has two meanings.[1] The first meaning is the result of interbreeding between two animals or plants of different taxa. Hybrids between different subspecies within a species (eg Polypterus endlicheri endlicheri X P. e. congicus) are known as intra-specific hybrids. Hybrids between different species within the same genus (eg. Scleropages formosus X S. aureus) are sometimes known as interspecific hybrids. Hybrids between different genera (eg. Amatitlania nigrofasciata (convict) X Rocio octofasciata (Jack Dempsey)) are sometimes known as intergeneric hybrids.

So any cross of two fish from different taxa is a hybrid.

BTW I realise Wiki isn't the bible on all known things, but it does contain a lot of useful information about taxonomy. I'm not too sure how up-to-date their Latin names are, but I haven't yet seen a reason to believe they aren't valid.

I think the Cross v. Hybrid argument put forward by Kamisan and Majinn is cogent and while possibly not meeting every taxonomic definition can be considered correct based on their geographic location. Malasian and Indo Arowanas have always been considered to be the same species with geographic color variations.

It wasn't until just this year that Schleopages Formosum was reconfigured and it is based on the slightest of taxonomic differences in the fish.

Here's another way of vewing this issue: The breeding of a horse and a donkey produces a Mule, a Hybrid. The breeding of an Arabian and a Quarter horse produces aa Arab/quarter Cross.

Breeding an Asian and a S. American Aro (if possible) would produce a Mule. Breeding an Asian and an Asian produces an Asian Arowana of a different color variant.
