These snakes have an active lifestyle in daytime finding their prey. As a defense mechanism, if threatened, they hiss loudly, vibrate their tail, and flattens their neck and body vertically though seldom bites.

Lifespan

Experts have a hard time knowing the average lifespan of these species in the wild, but the longest-lived Eastern Indigo snake in captivity is about26 years.

Eating Habits

Like all reptiles, they are also carnivorous. They tend to eat all living creatures as long as they can easily overpower it. In the wild, they make sure to kill their prey before placing it into their mouth while in captivity, breeders would always give them dead prey to ensure that they will not be injured if the prey would fight for their lives. The young’s would have the same diet but with smaller prey. They would usually wrap around their bodies into their prey’s body so that it will be easier for them to eat even though their prey is still fighting for their lives.

Breeding and Reproduction

The breeding season takes place at the peak of the winter season or from October to February where the temperature is around 50 to 60 degrees Fahrenheit. This is quite unusual for reptiles because for some, this temperature is too cool, that is why they hibernate. The mating happens in the sandhills.

For an average of four months, except that the female will lay about 4-12 large eggs with a 3 in. (75 mm) length, with an elongated cream-colored granular egg surface. Most likely, they lay their eggs in gopher tortoise’s burrows. Since they produce large eggs, the hatchlings are also large with an average size and weight of  40 cm (16 in.) and about (50 g) 2.5 oz.

Shedding Process

During the shedding process, it is not advisable to handle them because of their temperament. Beginner breeder would see the snake’s condition before shedding alarming because of their dull skin and blue eyes, but these are just normal, it will go back to its normal condition after 1-2 days and expect that the shedding process will take place. It is important to observe the way they shed skin, it should be removed all at once. If the skin is being removed in patches then there is something wrong with the temperature and humidity level.

To make sure that there will be no problem in the shedding process, make sure that your pet is always hydrated so that there will be no problem in excreting a lymphatic fluid that will aid in the shedding process. Make sure that their environment is also moist by spraying water on the sides of their tank. Once the skin has been removed, take it out from the tank immediately so as not to cause bacterial buildup.

Common Disease / Illnesses

Pneumonia and Respiratory Issues

Like humans, snakes are also prone to pneumonia and respiratory issues if the temperature that they are in is not optimal. It is also important to balance the right moisture and dryness on their tank. There are times when they need moist, especially if they are about to shed their skin, but most of the times they need a dry environment.

Pneumonia and respiratory issues can be detected if you notice that your pet has nasal discharge. Once you see that there is nasal discharge, take it immediately to the veterinarian so that they could give its first aid because if not treated accordingly, your pet will have hard breathing and its fatal.

Parasites Infestations

Parasites infestations can be avoided if your pet’s housing is secured with a cover or screen that will still give proper ventilation.

Parasite infestations are not fatal, but this is a clear indication that their environment is unhygienic.

Parasites love to thrive in a dirty, smelly, and chaotic environment. As much as possible, clean their tank at least once a week, especially if they are known to defecate more often. Aside from cleaning their housing, bathe them often will easily shoo away these parasites.

Blister Disease

These snakes should always be in a dry substrate most of the time. If they are too exposed to wet or damp conditions, their skin is susceptible to different skin conditions such as blister disease or it may cause lesions that may cause septicemia and other skin infections that may be fatal if not treated immediately.

When you handle your snake, observe their skin carefully, especially in the ventral side to check if there are blisters. If you notice blisters, you can apply some ointments that are suitable for snake’s skin or better yet take it to a veterinarian so that they could apply or treat it with antibiotics. Before taking it back to its housing, make sure that it is clean, dry and sanitized.

Anorexia

There are a couple of reasons why your snake refuses to eat, they are not active when the temperature is too high that is why they also don’t have an appetite for eating and when they are about to shed their skin. If you notice that the environment for them is just optimal and they are not exhibiting signs that they are about to shed skin there is a possibility that their lack of appetite in eating could mean something else.

Aside from lack of appetite in eating, anorexia is also characterized by difficulty swallowing and digesting food mostly that food that is hairy or feathery, they tend to vomit what they placed on their mouth and then swallowing it again. In this case, it is advisable to seek medical attention because it could mean something serious.

Egg Binding

If you are breeding in captivity, it is important to observe each stage from mating to reproduction so as not to cause any problems, especially when it is about time for them to lay eggs. The most common problem that snakes encounter in giving birth is the egg binding where the egg is stuck on the female’s organ if it is too big. It may be difficult for you to check if there are stuck eggs that is why you may need to ask medical assistance so that they could check the health situation of the snake after giving birth.

Egg binding is fatal because if the egg just stays on their organs, it may cause sepsis that is extremely fatal. It would also cause different irritations making your pet aggressive. This condition can’t be avoided, but through observation about the life processes your snake undergoes for sure, you would be able to maintain a healthy lifestyle of your pet.

The common disease or illnesses of snakes can be treated when attended to immediately. Once you see changes in their physical appearance and on their behavior, you must be able to determine if it needs medical attention or the factors that threaten their health is controllable. Most of the diseases of snakes would boil down to how their environment gives them comfort. If the environment where they are in is not conducive, there is a possibility that your pet will be stressed leading to a certain health condition but if their environment promotes comfort, mostly likely your pet will be happy and healthy.

Light and Temperature

These snakes have an unusual comfortability in the cold temperature of about 70-78 degrees Fahrenheit in captivity, but during a couple of hours within a day, it still needs warm temperature of about 85 degrees Fahrenheit where it can bask. The use of an incandescent bulb is just enough to keep their tank warm for a couple of hours a day.

Food

Water

Sound and Vibration

It is important to place them in a room or in a place in your house where these factors can be avoided so as not to bring out the aggressive behavior in them.

Substrate and Accessories

The excellent substrate for their tank is aspen chips, bark shards, cypress or fir together with fine sand. They also need to have trunks or logs where they can climb to bask. You also need to properly place the basin or bowl where you can place their water for soaking or drinking. It is advisable to at least provide these snakes with an environment that is just like their natural habitat.

Cleanliness

These snakes release watery waste frequently, that is why you need to constantly clean their tank to avoid the smell and build-up of bacteria. Make sure that the water will not overflow because if it overflows, the substrate will be damp and their skin will soak making it prone to skin diseases and fungal infections. Experts would say that of they are exposed to their waste for so long, it could also immediately lead to these skin diseases and fungal infections.
