I got an Ornate 9" (Measured today!) a Delhezi (Almost 7") and a senegal (9inches) I plan on adding more bichirs they are kept in a 90 gallon with tons and tons of filtration and UV power. I really want a fish to swim around the middle to top what do you guys suggest an Oscar maybe? Something that wont fin nip or be a punk to the bichirs is what im looking for I had to move my livingstonni which I love to another tank for fin nipping and picking on the bichirs.
