Here, you can see the color difference in the male and female. Female has pink on the belly.

Again, note the belly


Unfortunately, this pair of rams were my only fish from a reputable source that passed away. I'm not sure of the cause, as everyone else is thriving, and conditions remained stable. However, I do not believe I have a good photo of the male's fins vs. the female's. I will check, though.

Some things I have found out about IDing the gender of males vs. females are;
1) the females have a more of a rounded tail and the male has a 'V' shape with 'sharp' corners on them
2) the males have a elongated 2nd ray in the dorsal fin
3) the males dorasl and anal fins at the back are more pointed then the females
4) the females have more red on their belly compared to the males
5) the obvious, the females are thicker/rounder when mature and able to mate
I hope these also help with your sexing of them. If you have any pics that show the differences, I am letting you post them here.

There is also the ovispitor or "egg-tube" on the females, the little white tubey thing in their vent area. One of the best ways, as described to determine sex before buying is the pink belly. It shows that they were well cared for in the store and have a better chance of survival in the first week after acclimation.
