Anyone who has experience with Motoro Rays - do you have any clue why our Motoro is not eating? She hasn't eaten anything substantial for almost a week, but she still seems happy - she's moving fine, surfing in the bubbles, etc. She's acting quite normal except that she will sometimes chew up the shrimp or other seafood that we feed her, but then she spits it out. About the same time she stopped eating, we added a new fish to the tank - we thought it was big enough and fast enough to evade her, but the next day, it was gone. I am concerned that now she has the taste of live fish and she's being picky and won't eat the thawed out shrimp that she used to love. Any help or suggestions would be appreciated!! Thanks!
