I'm a first timer here, ooking for some ideas.

I have a planted 94 gallon tank that I have set up for South American Dwarfs. Right now I have pairs of Nijsseni, Cacatuoides, Agassizii, Viejita, and Borelli. I also have two blue rams and two Bolivian rams as well as a small group of Cardinal Tetras. I am looking to add some more fish but not sure what to add! I want some nice colorful species and maybe some mid to top swimmers! Keep in mind it is an open top aquarium..... So, no jumpers! ) I am not looking to keep only dwarfs so I am open to other ideas but would like to keep with the South American theme!

Any recommendations would be appreciated!

Thanks
