What are you feeding your sfe right now. The reason I ask, is because I have had a sfe for 2 years, and I have fed him a seafood mix I buy from an oriental food store. Recently I purchased some silversides for something different for the eel. He doesn't touch them. He grabs them and then spits them out. I guess he developed a taste for shrimp, cuttlefish and octopus, and now a fish just doesn't cut it. LOL. Your lfs should have silversides though. I have never heard of them in a grocery store.
