whats the point of running a BB tank with Rays?? is its so you can always see and appriciate the Ray?? because my guy is always burried in my sand!! im sure it makes him more happy being able to hid and play in the sand but geez i never get to see him lol but he is new to my tank (3days) he can from a gravel rock tank so he was never able to burry himself so is this just cuz he is new and just getting comfortable with his new surroundings??? plus i cant get him to eat yet from what i have seen he is a Motoro and he is 9 inches DIA. im going with a larger tank in a few weeks and woundering if i should go bare bottom or is it better to keep sand to make him more happy??? sorry for creating a debate if one occurs!! thanks and yes have searched!!
