#Sexing Method
1. Distinctive black marking on the dorsal fin indicates that it is a female. However, this is not foolproof. The same pattern does exist on some male Flowerhorns.
2. Observations on the shape of the genital papillae. V-shaped papilla indicates a male fish, while a U-shaped papilla indicates a female fish. Gently squeezing the abdominal region may reveal the papillae.
3. Male Flowerhorns will have broader body with higher dorsal, anal and caudal fins. It is also observed that male Flowerhorns will have thicker jawline and more distinctive body color.
