Hey guys. Iv recently just purchased a little female Potamotrygon motoro who is about 20cm in diameter. She's doing well and iv recently got her eating bloodworm, krill and mysis so far. Iv had her for about four days now and been told that I should give her a multivitamin with her frozen food?.., and was told to buy REEF LIFE-Aminovit by my local pet shop, to apply to the frozen food every week..? I know this is used in marine setups, but was wondering if it is suitable for rays? Does anyone have any experience with this product or are they all the same..? Or should I not use it at all. Please help 
Thanks Matt.
