I have almost read every thread here and have leard alot and i have read every homepage about rays i can find. Know i feel that i know enough too get my first ray. Of course it can go all wrong becuase im not an expert becuase i never had an ray and only read about them. Im not going to get a ray tomorrow becuase theres alot to fix before. I must get a bigger tank and a better filtration. Know i only have a 540L big tank thats 150cm long 60cm high and 60cm deep. So im going for something tvice as big (i hope soon.) But before im thinking about buying a big group of shrimps that i could breed in and maybe put in the same thank as the ray. Shouldent live food trigger the eating instinct of the ray and maybe mixing this whit live eartworms? Maybe i can get around a anorexic ray by this way and get a stabil food source in the tank for a short while? I realize that the shrimps in the tank is not going to bee long lived but i think thats it wort it. Or what do you guys think??
