I didn't sex mine, I actually adopted them from a store that was giving up on fish. They started breeding around 3" and that's how I sexed them lol.
I always passed them up at the store because they were drab in coloration, but I was mistaken. As they grow they get some nice green and red mixed in with the brown. Also, their easygoing temperament makes them ideal for mixing with other fish when compared with more aggressive cichlids! They're kind of like very peaceful oscars, but their behaviors are a bit less goofy than oscars.
