Introduction
The Blue-Tailed Skink, often belonging to the Plestiodon genus, is a captivating reptile known for its vibrant blue tail, especially prominent in juveniles. These fascinating creatures are sometimes kept as pets, and like all animals, their health and longevity depend significantly on receiving a proper and well-balanced diet. This comprehensive guide aims to provide you with all the essential information you need to feed your blue-tailed skink a nutritious diet that supports a long and healthy life. Keep in mind that young skinks and adults may have slightly different dietary needs, so we’ll cover those nuances as well. Understanding the specific requirements of your blue-tailed skink is the key to ensuring its overall well-being.
Understanding the Natural Diet of Blue-Tailed Skinks
To best replicate a healthy diet in captivity, understanding what blue-tailed skinks eat in their natural environment is crucial. In the wild, these skinks are primarily insectivores, meaning their diet mainly consists of insects.
Insects form the cornerstone of their sustenance, including various types like crickets, grasshoppers, beetles, and caterpillars. These provide essential protein and other nutrients vital for growth and energy. Beyond insects, blue-tailed skinks also consume other invertebrates, such as spiders, worms, and snails, further diversifying their nutritional intake.
While invertebrates constitute the bulk of their diet, blue-tailed skinks are also opportunistic feeders and may occasionally consume small vertebrates. This can include baby rodents or even other small lizards. However, it’s important to emphasize that these items represent a very infrequent part of their natural diet and should not be considered a staple. They also consume small amount of plant matter when available. Berries and soft fruits are consumed when they are available, but they only make up a small portion of the skink’s overall food intake.
Variety is a key characteristic of a blue-tailed skink’s natural diet. This natural diversity is important for providing a broad spectrum of nutrients, including proteins, fats, vitamins, and minerals, all essential for their health and survival. Mimicking this diversity in captivity is a primary goal when crafting a suitable diet for your blue-tailed skink.
The Ideal Captive Diet for Blue-Tailed Skinks
Replicating the nutritional richness of a blue-tailed skink’s natural diet in a captive setting requires careful planning and attention to detail.
Staple Foods
Insects should constitute the majority of your skink’s diet.
Crickets are a commonly used staple. Before feeding crickets to your skink, it’s imperative to “gut-load” them. This involves feeding the crickets nutritious food for at least twenty-four hours before offering them to your skink. This ensures that your skink receives maximum nutritional benefit from the insects. Dusting crickets with calcium and vitamin D supplements is also crucial to prevent metabolic bone disease, a common ailment in captive reptiles. Select cricket sizes appropriate for your skink; smaller skinks will need smaller crickets.
Dubia roaches are an excellent alternative to crickets, offering several advantages. They are more nutritious, easier to breed, and less likely to escape from enclosures. As with crickets, select appropriately sized roaches for your skink.
Mealworms and superworms can be offered as treats but should not be a staple food. They are relatively high in fat and can lead to obesity if fed too frequently.
Locusts and silkworms are also good options. Locusts provide a good source of protein. Silkworms are known for their high nutritional value, being rich in essential amino acids. Waxworms should only be given as a rare treat due to their high fat content.
Gut-loading of insects should be done before feeding to your blue-tailed skink. This is the process of feeding your feeder insect nutritious ingredients before feeding it to your skink. It is important because the nutrition of the feeder insect directly affects the nutrition your skink receives.
Supplemental Foods
Offer these less frequently to add variety and provide additional nutrients.
Pinky mice can be offered to adult skinks very occasionally. They are high in protein and calcium but also high in fat. Overfeeding pinky mice can lead to obesity and other health problems.
Small amount of boiled eggs are another source of protein that can be offered occasionally. Small pieces of fruits or vegetables can supplement their diets and add some variety. Some good options include berries, mashed banana, and leafy greens. However, remember that fruits and vegetables should make up only a very small part of their diet to avoid digestive issues.
Foods to Avoid
Certain foods are harmful or nutritionally inadequate and should be avoided.
Wild-caught insects may contain pesticides, parasites, or other harmful substances and should never be offered to your skink. Large amounts of fruits or vegetables can cause digestive upset due to their high sugar or fiber content. Processed human foods are toxic and detrimental for blue tailed skinks. Never feed these reptiles any human food. They don’t have any nutritional value for the animal and could cause health issues. Also avoid insects from pet stores not intended as feeders; these may have been treated with chemicals.
Commercial skink diets may be available, but their quality can vary significantly. If you choose to use a commercial diet, carefully research the ingredients and nutritional content and supplement with live insects.
Feeding Schedule and Portion Sizes
Creating a consistent feeding schedule is essential for your blue-tailed skink’s health.
Young, growing skinks require more frequent feeding than adults. Juvenile skinks should be fed daily.
Adult skinks can be fed every other day or every few days.
The appropriate portion size depends on your skink’s age, size, and activity level. A good rule of thumb is to offer as much food as your skink will consume in a fifteen to twenty-minute period. Regularly monitor your skink’s weight. If it is gaining too much weight, reduce the portion sizes or frequency of feeding. If it is losing weight, increase the portion sizes or frequency.
If you have a picky eater, try offering a variety of different insects or try gut-loading the insects with different foods to make them more appealing. Ensure the environmental temperatures are correct to stimulate appetite.
Supplementation: Calcium and Vitamins
Calcium and vitamin D are essential for maintaining strong bones and preventing metabolic bone disease.
Dust insects with a calcium supplement at most feedings, and with a vitamin D supplement a few times per week. Many calcium supplements will also include vitamin D. This is fine for your skink, but you may not have to supplement as frequently as if they were individual.
Many reputable brands offer calcium and vitamin supplements for reptiles. Research and select high-quality products specifically formulated for reptiles.
Over-supplementation can be harmful, so follow the recommended dosages on the product label.
Water and Hydration
Access to fresh, clean water is crucial for your blue-tailed skink’s health.
Provide a shallow water dish that your skink can easily access. Change the water daily to prevent bacteria growth.
Misting the enclosure can help to increase humidity levels, which can also contribute to hydration. However, proper ventilation is important to prevent respiratory infections.
Watch for signs of dehydration, such as sunken eyes, wrinkled skin, and lethargy.
Food Preparation and Handling
Gut-load insects by feeding them a nutritious diet consisting of fresh vegetables, fruits, and grains for at least twenty-four hours before feeding them to your skink.
Store feeder insects in a well-ventilated container with adequate food and water.
Use tongs to handle feeder insects to avoid being bitten and to prevent the transfer of bacteria.
Common Feeding Problems and Solutions
Refusal to Eat
Several factors can cause a skink to refuse food, including stress, illness, improper temperature, or a poor diet. Ensure that the enclosure is appropriately sized and has proper temperature gradients. If your skink refuses to eat for more than a few days, consult with a veterinarian.
Regurgitation
Regurgitation can be caused by overfeeding, improper temperature, or illness. Adjust the portion sizes and ensure that the enclosure temperature is within the recommended range. If regurgitation persists, consult with a veterinarian.
Weight Loss or Gain
Weight fluctuations can indicate dietary problems. Adjust the portion sizes, frequency of feeding, and type of food offered to maintain a healthy weight.
Impaction
Impaction is a blockage of the digestive tract. Prevent impaction by using an appropriate substrate (such as paper towels or reptile carpet) and by ensuring that food items are appropriately sized.
Conclusion
Providing a proper diet is paramount for the health and well-being of your blue-tailed skink. By understanding their natural dietary needs and carefully selecting and preparing their food, you can ensure that they receive the necessary nutrients for a long and healthy life. Remember the importance of variety, appropriate supplementation, proper portion sizes, and regular monitoring. Always research your skink’s needs before making dietary changes.
