Mine didnt appear to like each other but then I found I had a babies. It takes time, if your having them to breed your meant to put like 6 fish into a large tank and let them pair off naturally. Then remove each pair. You just have to be patient with them, theirs not alot you can do but make sure they have a nice clean tank with the right type of environment in. If your wanting them to breed make sure you have some wood in their preferable a wooden cave that they can breed onto. All fish are different and mine lived in a coconut shell with moss on top, they wud pull the moss off and make there own 'nest'.
