Blue/Black Aro discussion

[TheFishWrestler]

I was on another forum and a vendor said he had true black aros. So I questioned him saying I always thought blues and blacks were the same fish. He started to get all defensive and acting like an *** h@%e. Here is a link to the discussion. I am pretty sure that I was right that they are the same fish, but can some of the experts here read the discussion and let me know.

Black and Blues are the same arowanas. The average name is black arowana because when they are babies they are black with gold/orange accents and as they grow older they turn to their steel/grey (bluish) color as adults.

I have never seen a juvie Blue aro so can't tell you if blue and black are the same but from what i've read i think they are the same.

did some quick google searching. looks like he's right, its a different color variant. not a different species, but just the variation of the 'black aro'

i think this would be the brazilian black arowana

and the typical colombian "blue" arowana

I think it's just a color variant of the same species from a different collection point.
For example, S. Rhombeus (black piranha) has so many different variants from different region of the amazon river and some are more rare (less available in the hobby) than others which results different in pricing. some believe that some could be different sub species but has yet to be studied in detail. maybe same applies to black/blue aros.

Only difference is the level of maturity, this is what makes for the color variants. They will all end up looking the same if you provide the same lighting.

The pics really show nothing but large adult blacks out of water and young black aros under water.
