I had a pair setup in a species only tank and they bred like crazy from the time they were around 2 inches. Both parents tend the fry and will continue to hatch batch after batch with the older juvies helping in the rearing of the fry. I had mine with two very small rock caves (one cave on each side of the tank with a single large fake plant in the center and each fish took up residence in its own cave and they selected one cave to rear the babies in . It was so cool to watch. They have to be the best parents i have ever seen. Let me know if you would like to see a short video i took of them rearing the young, it shows the male or female going back and forth to rock house where the other parent was with the young. Pretty cool.
