On note about Sparky's gender, looking at his.. ehem.. probably isn't going to tell you much. Generally the differences between males and females in the fish world revolves around fin shape, body shape (females are chubbier), and the occasional breeding tubercules. Some cichlids will develope breeding tubes from their cloaca around breeding time. I checked Fishbase.org out to see if they had any M/F differences listed, but they didn't. However, they did have some interesting info listed about Sparky's electric organ.
"Active at night, feeding mainly on fish stunned by electric shocks. The electric organ, capable of discharging 300-400 V, is derived from pectoral muscle and surrounds almost the entire body. It is used both for prey capture and defense. Electric organ discharge (EOD) is intermittent and the amplitude increases with size of the fish"
More info. I guess it's a good thing he's a small little bugger!
