it has been done, it can be done, jus not and every day common thing. i've never done it, and i dont think anyone on mfk has done it yet that i know of. many of us are trying to but it isn't as easy as some cons or cichlids. it takes over 3 years for an aro to mature and even then, we dont kno if we have a male or female, so we gotta grow out a few n hope for the best.
