I have three Red Eared Sliders. I got them when they were babies.. they've always been great eaters and ALWAYS very active and nutty. Lately, however, the biggest of the three (they're all the same age but they're all different sizes now) has been acting SOOO lathargic (sp?). Like they would always just sort of hang in the water at night sleeping, but now the big one does that during the day too! And he just isn't nearly as active and always slow. I'm so worried. What can I do???
