To say they are easy breeders is an understatement. In 2006 I purchased a half dozen HRP's at a Grand Rapids auction. After co-existing with others in a 65 gal. tank for several months, would you believe, I had 3 pairs spawning in the tank, with each pair taking care of their progeny.
They do get quite colorful during the spawning dress (and not so bad otherwise) and I certainly enjoyed the experience.
