Thanks for the help!
Male rams have an elongated 2nd, 3rd and sometimes 4th dorsal spine. In larger fish, especially ones that have been in a tank for a while, if you don't see the elongations, the fish is a female HOWEVER, when the fish are new, sometimes during shipping and handling at the pet store or wholesale house, the male's elongated fins deteriorate so they look like females. If you are trying to breed them, put 4 to six younger fish together and let them pair off. Make sure you have a number of different places for them to hide and pair off without killing off their tank mates. If you can't wait, get some larger fish that you can better sex. Larger females also tend to have a more rounded abdomen from the eggs they are holding.
If you just want them to get along, put in more hiding places for security until they adjust to each other.
Hope this helps...

There are some exellent pics of the pair so you can see the difference in the dorsal fins between the two.
