Yes thats correct. Not only can motoro sp females produce huge litters, they are substantially cheaper than a black hybrid female. One can literally buy several in the place of one black female. Alot of times they will place 1 BD male among a pond of motoro sp females and crank the pups out. This is very common practice now.This is a very correct statement. At one point I know motoros were bring used as females only because of their size and the amount of pups they can pump out. A lot of the hybrids on the market are multi generation pups of parental hybrid. This ray here could easily be made up of 3+ different kind of rays of mixed lineage.
