Glad you finally got one EG, but i have some bad news for you Motoro's are one of the more aggressive rays and should not be kept with the smaller more gentle and delicate species like reticulatus, hysterix or laticeps as they will quickly start to bully and out compete them for food. Motoro's are best kept with more motoro's or other aggressive rays like leopoldis and henli's which can hold their own in aggression and feeding stakes.
