Any suggestions on South American fish that enjoy the top of the tank. I have a deep tank and I'm trying to fill up the top levels. I have 2 Female Green Terrors, 2 Silver Dollars, 2 Clown Loaches, and 1 Pink Cichlid. Someone suggested Gold Killifish because they like the top but they are from Pakistan I'm fairly certain. Want to keep this tank strictly South American. They all get along great and I have no issues only when the Green Terrors lay eggs they one gets crusty.
