I was wondering about feeding not because of time, but quality of water. How many times do you change your water for your spotted ray. This is my first ray, I did alot of research, but still dont want to do anything wrong, you know! Also did yours take to pellets right away, I am feeding mine silversides, about 4 full size ones cut in half both morning and night. Also when they poop do you clean it off the sand everyday or just let the filters break it down??
