i know ur no noob when it comes to rays like u stated. but before u kill it, would u at least try an make a thread an try an save it. i know ur water is perfect but whats perfect many ray keepers have different ideas of perfect. make a thread spend some time, post pics, water parameters, temp. tank setup what have u tried to feed, whats the worse than can happen. he dies, or someone might have an idea on how to fix it. anyone that knows rays an has been around the block knows we are all noobs, we learn things every day about rays. many things are still a mystery. maybe im wrong an u looked for advice on another forum but def not here. and any experienced ray keeper that thinks he knows it all shouldnt be keeping rays. so make a thread lets all ban together an try an save it. unless u just wanna kill it that bad,
