Mixing Aro

[Adz1]

so what i want to know is

is it safe to mix asian aro with south american aro?

and or what other options i have to lower the asian aro aggression towards tank mates.

thanks for any and all help.
opinions welcome as well.......

It should be safe as I've done it many times. Just makes sure they are the same size or the SA aro is even bigger. If the SA aro is smaller it will become jumpy if it will get harass by the asian aro.

As I suggest on your other tread. Get more pbass or more asian aros of the same size. I usually add them during water change as if you just add them right away and the aro will get excited and the harassment starts. Or both will fight.

SA aro=arapaima? Won't the arapaima out grow the asian aro and, assuming u have the right tank size, eat the asian?

Lol! South american arowana are black aro and silver aro. Arapaima is NOT even a true arowana species nor belong to the same Family.

BTW I have mix 4-6 feet arapaimas back in asia with some 18-27 inches arowanas and other fish. They don't get eaten.

Ah my bad, i thought SA was arapaimas...and well with the size of arapaimas, i've never looked into it.

Arapaima is NOT even a true arowana species nor belong to the same Family.

Actually, Arapaima gigas and the two arowana species in the genus Osteoglossum are in the EXACT same family; Osteoglossidae.

To the OP, I know you see a lot of tanks with more than one arowana in the tank, but it is my opinion that only one should be kept per tank and the Osteoglossum sp (SA arowanas) should never be purchased, do to the fact that they obtain lengths exceeding 99.99999999999999% (or there abouts) of most private aquariums.

Lol! That's where you're wrong. You still probably reading the old literature. The true arowana species belong to Osteoglossidae which are the asian arowanas, south american arowanas and the australian arowanas. The arapaimas along with the african arowana belong to Heterotididae. Both family belong to Osteoglossiformes. Both family were actually classified in the same family before but the expert separated them.

Here, learn scientific classification...

http://en.wikipedia.org/wiki/Biological_classification

It goes...

Family
Genus
Species

And they all belong to the Family, Osteoglossidae.

LOL!!!

Lol! That's where you get information...? I know about the scientic classification already.

You should contact Laurent Pouyand or Heiko Bleher and ask them if they belong to the same family.

There are many debates about the arowanas and arapaimas. As some considered them in the same family and divided in two subfamilies as they were classified before. Some considered them to be separated as they just separate them just few years ago.
