No worries guys I am well aware of the size, diet and husbandry requirements of this ray. I have kept many rays in the past pdrs, castexi, motoro, scobina, hystrix and mantilla. As far as a pond setup, well unless you are keeping a smaller ray (hystrix, scobina etc..) almost every ray will need a pond at maturity. I have seen motoros that exceed 2' diameter and leos at 30" plus!
