Since all those fish are mid level open water swimmers, I would not do it in any thing under say a 150g or bigger. I do not think that the fish will bother each other. But they would be cramped in the same level of the tank. I second the pictures. I have been asking ever since you posted about getting the cuda's.
it will work.
you will have aggression from the payara,but it usually works out.
unless you have one that REALLY hates silver fish.
ive seen some like that...slaughtered everything silver.
just try it.
usually it works.
