The thing is that it is a male Flower were talking about, and a female Motoro. As far as ive read, the males dont get as big as females, thats why i thought this combo might be good. And also i would love to have something rare and different in my pond, i love my rays, but lets face it, motoro`s are not that fancy. For me i think Flower rays are one of the nicest rays out there. And since this is a male, that dont get as large as females, it seems perfect to me.
