I have been doing alot of research on fireeels and other kinds of eels. I have been really wanting to get a fire eel, or some type of eel for my tank. The lady at the pet store told me that, she owned a tire track eel and it ate everything it could fit into it's mouth, even a tiger barb. I read on the net that tiger barb's was a tank mate for eels. Then my friend told me that he owned a zig zag eel and it left all of the fish in the tank alone. So my main concern is that does anyone think that would a fire eel or some kind of eel have for lunch all of my other fish, or would it be fine?
