activity for the top of my tank

[jakester334]

So for my 40g breeder ive basically added fish for the middle and bottom level of the tank. Was wondering what fish /fishes I can add that would go with the fish I currently have for the top of my tank???? Current fish are 2 angelfish, 5 kuhli loaches, 2 german blue rams and 1 bristlenose pleco.

Thanks
