Forgive me if I'm wrong, but unless you're talking about a huge tank I feel like this is an accident waiting to happen. Angelfish are slow and graceful, even at full speed they're a pretty slow fish and I feel like they'd get injured by the silver dollars if they were to start darting around.
I have (what I believe to be) metynnis hypsauchen which are half the size of redhooks, and I couldn't imagine keeping them with angelfish because of how quickly they can move. If I ever kept them with angels I'd either want a HUGE tank, HUGE angels or both - probably both. Even then I'd expect wake up one morning to an angel with a broken spine sooner or later.
Disclaimer: this is solely my opinion. I do not know everything nor do I claim to. I'm here to learn just like the next guy.
Otherwise, great job Alex!
