They are really similar fish except the Brown Knife is less aggressive and smaller so a much better choice for your tank. They should be fine together because I keep a BGK and a Fire Eel together with no problems. For a diet my BGK likes ripped up shrimp, brine shrimp, and his favorite food is blood worms(make sure it is frozen food, if it doesn't get to the bottom it won't be eaten). Some can also be pellet trained but I wouldn't count on it, usually when full grown.
