:dunno: i am trying to sex my jack dempseys. one has darker skin with vibrant colors and red on the top of the dorsal fin. the other has lighter skin with less vibrant colors and does not have red on the dorsal. can anybody help me?
Sexing the dempsey is rather simple. Males will be larger and have longer more pointed fins with very little blue on the gill cover if any and will be in dots if its present whereas the female will have splotchs on her gill cover and have less color throughout the body. The female also tends to be more "squat" in shape.
