If your baby red-eared slider isn't eating, you can try dangling food in front of it to entice it to eat, or you can stimulate it to eat by feeding it other turtles. However, if your baby red-eared slider isn't eating because it's not used to its environment or is unwell, you should let it rest for a while and change its water regularly.
How to get Brazilian turtles to eat
Hold the food in place with a toothpick or tweezers and dangle it in front of the baby red-eared slider to attract its attention. If the turtle runs away, don't chase after it; wait a while and try again. After a few tries, you should be able to entice it to eat.
The baby red-eared slider's refusal to eat might be due to a lack of security in its new environment. In this case, only by increasing its sense of security will it be willing to eat. To address this, place the turtle in a quiet, relatively dark place and let it rest for a few days.
If you have two red-eared sliders, you can feed them together. Once one turtle starts eating, the other will follow suit, because turtles trust their companion.
When a baby red-eared slider is unwell, it will lose its appetite and refuse to eat. Factors such as low water temperature and poor water quality can cause discomfort in turtles. In this case, the owner can adjust the water temperature, change the water, and then try feeding the turtle again.
