Hi ,I have two axolotls have had them 3 months. They were eating 3 times a week ,but for the last 7 days have refused all food.I have tried worms ,chicken,frozen cubes of ox heart,fish slices of whiting..they used to eat the worms and ox all the time ,now nothing .How long can they survive without food.Their water is abit warm at 23 but hard to get down. Has anyone got any ideas. Thanks NELLIE
