There's a lot of evidence that SFE's diet switches more towards fish as they get older. Take a look at its teeth, I've read that as they get older their teeth become more like those of fish predators than the molar type teeth associated with crustacean eaters.
One of the reasons people may be unfamiliar with this fish's adult diet is that most SFE's do not reach adulthood in home aquariums. My boss at my old work had a SFE for about ten years. In the end, it was in a tank alone with a lion. If a fish became too aggressive in one of his other tanks, it would be placed in this tank. According to him, it was always the eel, not the lion that got the fish.
