The guy in the shop did you a favour.If he's got the ray taking pellets then your onto a winner,pellets are very good for bulking rays up and generally contain most of the ingredients for a long and happy life suplimented by the usual frozen foods as well ofcourse.For now get those pellets down the ray until hes got good body mass,only then do you need to worry about alternatives.If after several weeks the ray still hasnt gained weight then this could point to internal parasites which will need to be dealt with,prazi springs to mind as a treatment.well she ate a earth worm pellet today and i did my reasearch and i saw it eat in the pet store so i knew i ate i called every place i could think and all i found was a guy who sells frozen blood worms but i asked the guy i got the ray from and he said when he first got the ray it only ate shrimp and he weand it to pellets so it should eat shrimp wish me luck![]()
All the best with your ray.
