please tell me which is the most accurrate way of sexing [BUTTERFLY RAMS ] is it colour or the shape and size of the dorsal fin or maybe something else.
From my understanding, the one factor that seems to be constant in every reliable source is the blue speckles in the black blotch on thir sides. The blue flecks means a female. All other factors (fin length, color, size, shape) is tough to make a call on due to individualism of fish.
