I bought my first FW ray a few weeks ago, she's a "teacup" stingray about 10 inches long. I've been feeding her ghost shrimp and have tried to feed her feeder guppies, but she only seems to go for the shrimp. It seems as though she's not very good at catching food yet, because she seems to have a very hard time catching the shrimp and won't go for the guppies at all. I would like to figure out something I can feed her besides shrimp that she'll actually eat but she doesn't seem to be interested in anything else. I need suggestions on some type of food that I can buy in larger quantities so that I don't have to go to the fish store every day to buy her shrimp.
