Most pet salamanders eat once per day, although that number varies depending on certain factors. The salamander's age, size and species are factors when planning a feeding schedule. The temperature of the tank can also affect the salamander's appetite.
When feeding a salamander, the food should be limited to the amount it will eat in one feeding. Once the salamander has finished eating, all of the excess food needs to be removed from the tank.
Feeding a salamander at least once every day is preferable, but there may be days when it is not hungry. Some pet salamanders only eat two to three times per week. Individual salamander's eating habits determine the best feeding schedule.
