As much as I agree with this statement, here are some counterpoints.
I have seen plenty of people keeping pbass in tanks as small as 125's. Does that make it right....no. does that make it doable...yes. I think 3 pbass would be alright in a 220 for while. They grow pretty fast but once the hit 12" their growth slows dramatically. I'm not saying it would make it to 4 years, but it would be good for 2-3 id imagine.
The juruense catfish sounds fine to me. I keep a 220 CA/SA tank and I had a thread about these and people said it would be fine with my tanksize, and I agree
I agree the aro is out of the question. I really want one too, but I know that a 6x2 tank could house it for a very short period.
Realistically if you stock this as you plan then it will be nothing more than a growout tank for future monsters. And unless you plan accordingly it can get out of hand quickly. If you are anything like me you get very attached to your fishy friends, and its very hard to get rid of them at that point. This is the main reason people end up with drastically overstocked tanks. They mean well, but just can't house their pets properly.
If it were me, my stocklist would be:
2xPbass
1xjuruense catfish
3xbichir (whatever species you prefer)
1xflagtail
And maybe a large growing pleco (again up to you)
HTH!

I don't understand your logic there... The pbass are okay, despite their enormous adult size and high level are activity because you have seen them kept in a 125 gallon; a juruense, which could grow to around 36" with a very thick body, can be fine in an aquarium that is only 24" wide.......... but a silver arowana, also topping out at around 36", with the ability to turn around in about a 36"x12" area seemingly effortlessly, is completely out of the question? I have seen them kept through adulthood in 180 gallon tanks with no issues whatsoever, so why are they so different?
