Just give them a litte time, you'll find out which one is the
strongest and you'll have one. How big are they now?

From what I understand they are very difficult to breed in the
aquarium, just to aggressive. These are some of the meaner South
Americans that I have seen. The'll easily get at least 10" in lenth
and live quite a few years. If they don't eat your plants they'll
uproot them because they like to arrange the gravel their way, not
yours. I can't remember what their ideal ph and water hardness is
right now, but are hardy enough to adapt to about anything.
