Understanding Why Your Crested Gecko Is Not Growing

Before diving into the potential reasons for stunted growth, it’s essential to have a basic understanding of how crested geckos grow and develop. Crested geckos, like all living beings, go through different growth stages throughout their lives. The growth rate of your gecko can vary depending on factors such as age, genetics, and overall health.

Age and Growth Rate

The age of your crested gecko is an important factor in determining its growth rate. Young geckos typically experience rapid growth during their early months, while growth slows down as they mature. It is essential to monitor your gecko’s growth at different stages to ensure it is developing as expected.

Environmental Factors

The environment in which your crested gecko lives plays a crucial role in its growth and development. Maintaining a suitable habitat is essential for supporting optimal growth.

Temperature and Humidity

Crested geckos are native to the tropical regions of New Caledonia, and they thrive in a warm and humid environment. Inadequate temperature and humidity levels within the gecko’s enclosure can negatively impact its growth and overall well-being. It is essential to provide a temperature range of 72-78°F (22-26°C) during the day and slightly cooler temperatures at night. Additionally, maintaining humidity levels between 50% to 70% is vital to prevent dehydration and promote healthy growth.

Nutrition and Diet

A well-balanced diet is essential for promoting healthy crested gecko growth. Nutritional deficiencies can lead to stunted growth and various health issues. In the wild, crested geckos primarily feed on fruit, nectar, and insects. As a pet owner, it’s crucial to replicate this diet with commercially available crested gecko food, supplemented with appropriate fruits and insects. Providing a varied diet ensures that your gecko receives all the essential nutrients required for healthy growth.

Health Issues

Underlying health problems can hinder a crested gecko’s growth and development. Some health issues may not be immediately apparent, so it’s essential to observe your gecko for any signs of illness or discomfort. Common health problems that can affect growth include respiratory infections, mouth rot, and skin infections. If you notice any unusual behavior or physical symptoms, consult with a reptile veterinarian for a proper diagnosis and treatment.

Parasitic Infections

Parasitic infections can sap the nutrients from your gecko’s system, affecting its growth and overall health. These internal parasites can cause digestive issues and reduce your gecko’s ability to absorb nutrients from its food. Regular fecal exams by a veterinarian can help identify and treat any parasitic infections.

Calcium and Vitamin Deficiencies

Inadequate calcium and vitamin intake can lead to metabolic bone disease and hinder growth. Crested geckos require calcium for proper bone development and muscle function. A lack of calcium in their diet can lead to weak bones and deformities. Dusting their food with calcium powder and providing a calcium supplement in their enclosure is essential for preventing deficiencies.

Stress and Agitation

Stress can significantly impact your crested gecko’s health and well-being. Environmental changes, handling, and excessive noise can cause stress in geckos, leading to decreased appetite and slow growth. To minimize stress, provide a quiet and calm environment for your gecko, and limit handling to avoid unnecessary agitation.

Enclosure Size and Setup

An insufficient or overcrowded enclosure can impede your gecko’s growth and limit its physical activity. Inadequate space can lead to stress and discomfort, which negatively impacts growth. Ensure that your gecko’s enclosure is appropriately sized for its age and provides ample space for climbing and exploring.

Handling and Interaction

Frequent handling and excessive interaction can cause stress, disrupt your gecko’s eating habits, and hinder growth. While handling can be a fun way to interact with your pet, it’s essential to do so with care and in moderation. Young geckos, especially, should have limited handling to prevent stress and promote healthy growth.

Genetic Factors

Genetics play a role in determining a crested gecko’s growth potential. Each gecko is unique, and some may grow at different rates due to their genetic makeup. Some geckos may reach their full size earlier, while others may continue to grow at a slower pace. Understanding and accepting these genetic differences will help you better appreciate your gecko’s individual growth journey.
