Schooling fish for predator tank?

[Jdk]

Hi, I just recently had a 450 gallon pond and now is stocked with 2 plecos, a silver arowana, and a pair of oscars (all of them are around 9-15 cm). Soon to add a peacock bass, 3 polypterus endlicheri of which 2 are albino and a florida gar which are all still in a 40 gallon tank as they are all still a bit too small to be able to survive in the pond(around 8 cm each). I was thinking of adding some schooling fish that will do ok with all of them. Ive thought of piranhas but am scared that they might fight with the others and is too risky. Ive also thought of getting solver dollars but not so sure about them surviving in there. I will be glad to listen to any suggestions!
Thanks!

I’d pass on piranhas. Maybe some large bala sharks, tin foil barbs, wide bar sd’s, and brycon.

I have red hooks. I really like that they are from the same region as the bass and they can take a serious beating and bounce back.

I'd say sds would be good or tinfoil.
