Eels are awesome. Not sure which you would get, but I have witnessed in one case a Tessalata (Sp?) eel I think it was eat a shark. It was at a 1000 gallon pond at my LFS. The eel went after the foot long shark and killed it. Probably rare but I just thought I should share it.
Possibly wear gloves when putting your hand in the tank? Something that can't get into the tank and harm it from the gloves.
