well the retropennis i got is about 4 inches there is a crap load of hideing spots. but the jadian would kill the polys right?

Jadian? You mean jardini? He could very easily kill them just to kill them, but maybe not. It's definitely a risk. Much more of a risk with a jar than a silver.

Not all jardini are killers. All aros have different aggression level. I have a green a 15" jardini with a 13" green asian arowana and some polypterus (12"-18") and ropefish. Even clown loaches at 7" are not being bother. Jardinis are become aggressive because they are being kept in a small tank with only a few fish as tankmates.

Here's my 15" jardini.

The aros and tankmates on the pics were taken on a 310g but now I moved them to 535g now.

...or they're not aggressive because they're in an overcrowded tank. Arowanas in general are known to be aggressive towards their own kind. Keep a Jardini busy with a school of other Arowanas and the story changes a bit. Keep them singly, as I prefer to keep them, and they have nothing to worry about...they're the king of the tank. I've always preferred to keep Arowanas singly because that way you have a perfect showpiece. Keep a group and there's almost always some level of fin shredding and damange.

My Jar was not in a small tank for his size...72 x 24" and I couldn't keep anything with him. He was by himself and he had plenty of room.

It all boils down to what you want...a knot of fish swimming around in a tank that can't go far without bumping into each other or this:

Most arowanas especially asian aros and aussie aros become very aggressive to the point of killing it's tank mate if it's been kept single when it was young. That's why I keep aros together of more than 4. They just keep swimming and not even show aggression to each other. But if kept 3 or less then you will expct some fin nip or fighting.

That Jardini was kept in a community, all the way up til about 12"...then it started killing off tankmates. It killed or nearly killed some of the most aggressive fish out there...Trimaculatus, Cintrinellum, etc.

That's when I decided to make the tank into a single species show tank. People would come into my house and not even take a second glance at my Ray tank and dropped jaw on the single Jardini tank.

Many people don't have the room or money to have an adequately sized tank for a group of Arowanas. I certainly don't have public aquarium funds. But, many people can afford to have a 72 x 24" tank...which can accomodate a single Jardini. And like I said, it also boils down to preference...I just like them kept alone and perfect. Great for photography.

Only if I have enough space at home to keep lot of tank. Ten I'll put them separately and turn them as a show aros.
