55 gallon bichir and oscar?

[ClownKnife28]

K, no oscar for me. How aggressive are the gold saum and severum? Are there any totally non aggressive non predatory fish that get big enough to keep with the delhezi that look good?

I have a gold severum with my senegal bichir. No problems. It will easily get large enough to be with your delhezi. They grow about 10-12 inches long and they are tall fish. They love to eat green veggies. (I feed mine romain lettuce twice a week and frozen blood worms, frozen krill and cichlid pellets the rest of the time.) No experience with the saum.
