I have an electric flame scallop that seems to be doing well for about 3 months now. It likes to situate itself in reasonable flow and creates a little nest in the sandbed. I am not sure about the differences between the electric flame and regular flame as far as requirements and life longevity go but I sure enjoy mine. I add "combo-vital" to my tank every second night and I believe it is eating.
