Leaving the light on at night may result in hyperthyroidism, a glandular disorder. Disease often results from opportunistic pathogens or parasites, which take advantage of turtles weakened by stress, malnutrition, or improper physical environment. Prevention of disease is best accomplished by providing the recommended physical environment, shelter features, and diet. This is the most important responsibility of the turtle custodian. Consult a veterinarian immediately whenever you suspect that your turtle appears ill or has been injured.
Turtles are susceptible to pneumonia and other respiratory ailments.
Symptoms are inactivity, runny nose, labored breathing and loss of appetite. Healthy turtles do not move the head and forelimbs in and out to facilitate breathing. Chronic nasal discharge or raspy breathing should receive veterinary attention. Respiratory problems are sometimes treated with antibiotics. Parasites are also common in turtles.
