I'm really not the one to answer this question because I've never seen radiata babies, but I THINK these are Star tortoises?????
Stars and Radiateds don't eat animal protein, and "turtle" food has animal protein. But you CAN feed manufactured TORTOISE food along with the fresh greens, weeds and grasses.
They are eating cucumber, one guy eats tomatoes also, today I tried giving them rose petals, but they had a bite only and continued with cucumber. They won't eat spinach also. Pl help with food.
