motoro stingray strange behavior?

[dparks87]

I have kept several Orinaco marbles and though I can not say with confidence that they do not grow as large as motoro they sure do grow slower. A 180 will suffice for some time, just keep the water clean. I would not even worry so much about the sand to be honest I used both play sand as well as carib sea moonlight white sand and my rays have done very well on both.
