Is it normal for gecko abdominal skin to turn yellow?
Gecko's abdominal skin color can be different, usually gray or white. Not all geckos have yellow belly skin. However, the color of gecko abdominal skin is influenced by many factors, including species, age, sex, environment, diet and so on. Therefore, if the skin on the abdomen of the gecko you see is yellow, it is normal in some species or specific individuals. If the skin of the gecko's belly has abnormal colors, such as red, black or other abnormal colors, it may indicate that the gecko has health problems and needs to consult a veterinarian in time.
