Blue/Black Aro discussion

[juneblood3]

The thing is, what determines a different colour variety? People who breed and sell fish love to make up different names for things to make them more marketable and saleable, and will try to pick up on all the different colour varieties they can find. But from a scientific point of view they're all the same fish unless described as a different subspecies.

The fact that the seller tried to say that "normal" black aros are a colour variant shows how utterly clueless he is. If I had more time I'd track down the taxonomic descriptions for O. ferrari and O. bichirrosum and ask him to read them and back up his claim with fact, however I have a life (and work!) so can't spend hours trying to rid the internet of idiots....

^^^ this is basically what I was getting at.

I think my IQ dropped 20 points reading this thread.

In other news, I've decided that my Aro is actually a purple Arowana. I will sell this rare new species for $2500.

Common Dave, you know its just a color varient that hasn't been exported for 32.6yrs.

On a serious note... anyone seen the black arowanas at the Shedd Aquarium? Identical to the ones in the fishing pictures posted. Just mature black/blue aros IMO. Same ones I've seen every year since I've been looking at aros.

just some info ive found on this subject around the web. but who knows what you can believe these days.

and another thing worth mentioning, the differences in water parameters in the countries may be part of the reason behind the difference in color. so in the aquarium, its a possibility they will look the same! even more food for thought

Black arowana orignally came out of Brazil,,,,,,,they stopped exporting them around 2004-05, then,
Blue arowana started come out of Colombia and are a black arowana slight color varient and now classified as Osteoglossum cf. ferrerai-------( .cf meaning it's a varient)

The Colombian varient has more yellow/orange in their dorsal, anal and tail fin,,,,,,,,,most have a better blue hue than the older black arowana from Brazil as they grow from sub-adult to adult.

Black aros get their name from their juvenile color form as do silvers.....calling the older black aros blue was a decoy strategy used by the exporters to get the already banned for export species out of the country...as for color varients between collection points...that seems true with most species coming from south and central america

in my opinion there is just one fish,call it black,blue,purple,whatever.With that said the sellers price at that size is cheap if your looking to grow out a cool small black,blue,purple,etc.I am not sure why the seller can't just post up black/blue arows 6 inch for sale wild caught and leave out all the drama that just gets everyone upset.

give me a year or two and mine should be big enough and I'll take some pics

Why did you buy some of these so called Venezuela black aros?

Thanks for knowing you're all talk and contribute nothing substantial to back up your claim. Like EZ said the "black version" hasn't been imported in over 15 years so it's pretty obvious then on one has it to take a picture, inside or outside the tank.

So if the black version hasn't been imported in 15 years, what is he basing his claims on, someone's memory? Maybe he had been fed some mis-information. He describes his baby blacks, and that is how all baby blacks look. you can even look at the pics in his sale thread.

Now if you really are interested and not just trolling, I have several threads that show the progressive growth of baby blacks, for you to view. These babies(which look the same as EZ's) grow into what is has been described as "Colombian blues" which that idiot EZ is claiming are just a version of silver aro. So I really don't see where anybody can argue that EZ knows what he is talking about.

heres a 16in black aro thats pretty black to me, http://www.monsterfishkeepers.com/forums/showthread.php?t=324414&highlight=black+arowana no way its over 15 years old if the so called black version hasnt been imported in that long

That look is typical of lighting, mainly the effect is seen with Hagan brand powerglo lamps. I have pics of my black under the same light, I'll find and repost later.

have you read anything in this thread? for the 50th time, nobody is arguing that it's a different species. the seller is claiming that this is a different color variant of Osteoglossum ferreirai, that comes from a different location.

The seller is claiming his are from Venezuela, I cannot find anywhere that supports that there are any arowana in venezuela.

Yeah I saw those too, that info just comes from a member in another forum. Nothing real to back up those posts. Except there are a couple references to the ban of exporting blacks from Brazil. According to fish base the only country the black aro is indigenous to is Brazil, not Colombia. Though Black aros are said to come from the Rio Negro river, which has it's origins in Colombia.

well the price was cheaper than any where I've seen so it doesn't matter to me where the collection point was.
also, when I picked up the fish I was told that these were from Brazil, not sure where the Venezuela came from.
