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
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.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.
