Tank is 8x4x2 LxWxH
Stocking is:
1 silver arowana
1 granulated catfish
1 pacu
1 dovii or jaguar ( depends which on I keep)
1 Texas cichlid
1 blue umbee
And a few silver dollars

I'm not familiar with all fish so I only respond on what I know.

A Dovii / Jag might kill all of that stocking.

But the Pacu get huge and very quickly, from what I read they're like sponges and when they hit the water they grow very fast like easily 2- 2.5ft and then slow down in growth

when all fish are full grown the space they have might be to small.
 
It's not gonna work. One as said above pacus can grow fast and turn into big powerful fish that can easly break a tank ( I know from experience on that one). The granulated cat also gets way to big. As for the cichlids if you put a umbee and a dovii and both turn out to be males there gonna kill each other. Just my opinion tho. If it was me for cichlids I'd do more Viejas and other peaceful larger cichlids synspilium, pearsei, ect. As for a cat I'd get a megaladoris irwini. Still get that prehistoric look but doesn't grow as fast
 
Because this tank (almost 500 gallons) will be considered adequate for those fish, by many people.
I think this would be an interesting experiment to see if it really is.
As long as you agreed to honestly and regularly report which fish eat each other, which ones fight to the death, which die of stress related diseases, and how long it takes for some to outgrow the tank. (such show long it takes for the pact's dorsal area to grow above the waters surface)
I have my theories but I think your tank and its dynamics could be an eye opener.

Agree with you, although I think we can guess pretty close the death order. Dollars and Texas first, assuming the umbee and dovii are grown out a bit to not be catfood it's a toss up which one takes out the other. Shortly after the aro gets it. If given enough time to grow the pacu may take out the umbee/dovii, if not it'll most likely be stress killed. So what's left is a big cat and one of either pacu/umbee/dovii. And given time, if it's a male dovii the cat will be in danger.

This order seems about right. Like duanes said though, it would be an interesting study on the aggression levels as long as the fish are typical specimens of their breed. As long as the on-goings were reported truthfully. I personally wouldn't want to deal with that level of aggression though.
