1. price not that great but okay for pet store.
2. it will take awhile for it to out grow the tank.
Is it male or female ? the females get bigger and tend to grow faster.
My tank is the same footprint. When I was doing my research people were telling me that a pair of Motoro's would prob be fine for 5/6 years in the tank.
I don't know whether it is male or female. Steve_b, do you have Rays now in your tank? for how long and how big are they now?
