Cockatoo aggression

Seems I'm losing smaller fish in a 20gallon. Currently stocking one large male double red and a juvenile male njiseni along with a pair of orange flash. Since introducing the pair it seems the largest male has claimed the female and now I'm pulling dead fish out every other day. I had 3 smaller fish from a previous batch of fry and 2 baby sunfish all turn up dead in the night. I don't wanna lose the njiseni or the new male. Should I just move them or can they handle themselves?

I cant imagine having more than a pair in a 20 gallon. I'm cautious about doing it in a 4 foot 75 gallon.

Understood. If they make it thru the night I'm moving them in the a.m
