I have 3 red eared sliders in a tank and have had them for about 4 years. I feed them turtle pellets most of the time but sometimes i give them Rosy Red fish. Iv been wanting to give them more but no one seem sto have them anymore. Someone at petco said that they with eat these small comet things if the turtles are big enough. I bought some of the comets and brought them home but im not sure if the turtles are big enough to eat them and i dont want them to choke and die. How do i know if the fish are small enough. They are about 2x the size of the rosy reds i used to give them?????????????
