The Iriatherinas feed primariy from the surface or the top 20% of the water column. They will go down to the bottom but do that reluctantly. So if the CPDs and the Darios can live fine together they will do absolutely fine with Threadfins.
Also combining these 3 fish basically fills the bottom/middle/top of the water column with fish that naturally stay in the respective zones.
