This is a specific care sheet for Blood Pythons, a subspecies titled (Python curtus brongersmai). For more of this species see Category:P. curtus.

Blood pythons are heavy bodied snakes. What makes this snake so unique and unlike other snakes is that its girth is huge relative to its length. A thick, muscular body makes constricting simple for this massive, yet relatively short snake. Its head is small, broad and long compared to its body size. Adults typically get their adult colors at two to three years of age.

This snake is for the intermediate keeper. These tropical snakes have very strict temperature and humidity requirements as well as a variety of temperaments. Without proper attention to their needs, this snake can take a bad turn quickly as a youngster. The most challenging part of owning this snake is, unmistakably, bringing it up from a young age. Besides needing exact humidity and temperatures, feeding can also be a challenge. The acclimation period can be most stressful because these snakes can make trying to feed a finicky ball python seem like a sunny walk in the park. Bloods get easily stressed and may react by not feeding regularly or having bad sheds. Keeping an observant and watchful eye on their behavior is necessary for identifying problems, as well as preventing them. Bloods are typically not as active as a common boa, for example, and an experienced keeper is the best defense. A common boa may give some noticeable signs that they may be ill by their activity level. The lethargic blood will give fewer signs. A few years of keeping other types of snakes would be ideal preparation before taking on a blood python.

Blood Pythons Coloration

Malaysian (Malayan) Blood short-tailed python (curtus brongersmai):Receiving their name due to their Oxblood or dark red coloration, most consist of dominant reds and yellows.

Borneo short-tailed python (curtus breitensteini): Most have orange eyes with black pupils, with the body consisting of dark browns, black and yellow coloration. The head is usually a light opacity yellow or brown, occasionally being a light orange.

Sumatran short-tailed python (curtus curtus): The smallest of the bloods, this one is commonly referred to as the “Black” Blood Python, for it typically has the darkest colors of all the bloods. Blacks have orange eyes with the blood trademark stripe beneath the eye which goes down the face toward the jaw (most bloods have this stripe on the eye). Blacks colors will generally become darker with age, predominantly black with dark grays in adulthood.

Sarawak short-tailed python (curtus breitensteini): Generally brighter, a dark burnt orange color with marble-like patterns, yellows, golds and copper-like colors.

Housing Blood Pythons

Young bloods do very well in an appropriately sized cage. It’s very important to create a safe and secure environment for a young blood because they are very shy and sensitive, and they need to feel that confining security. A 20 gallon cage works well to start them out or approximately 10 inches wide by 15 inches long by 5 inches tall. (If you have very young blood, or newly hatched, it may be necessary to use an even smaller container for feeding.) Putting a blood in a cage that’s too big for them might be convenient for the owner, but not the blood. (I have yet to cross a blood that is claustrophobic.) For adults, a cage which is long enough for at least half of the snake’s length is adequate. Ideally, a cage which is the length the same as the snake’s length will be even better. The width needs to be wide enough to allow the blood to turn around with ease. It’s been said that a cage which allows the blood to extend to its full length helps diminish the onset of respiratory problems. Depending on the type of blood, 4ft to 6ft long by 2ft. to 4ft. wide by 10 to 20 inches tall enclosures work very well for adults. (Keep in mind, if you do use a lamp as a heat source, the height of the cage will be a factor for the actual amount of heat the blood receives. Once again, it’s very important to have a good temperature gun handy for any reptile you own.) Plastic sweater box containers (like Rubbermaid) retain humidity very well. They are also user friendly for making holes for the necessary amount of ventilation. An aquarium with a screen mesh top provides good ventilation, but obviously will not retain humidity quite as well. Pegboard works well, too. Fiberglass, wood (smooth wood, not porous; remember, you’ll have to clean it!), hardboard, PVC, pre-fabricated, plexi-glass or any other heavy duty non-corrosive material will work for an adult blood. No matter what type of material the cage is made out of, make absolutely certain it is escape proof! Bloods are 100% pure muscle. Housing multiple bloods is not recommended, but if you do decide to (and they get along), be sure to multiply the cage space by one quarter.

Cleaning Blood Pythons

When cleaning, use a diluted detergent like Tide or Chlorox and/or 5% household bleach. Rinse with clean water and dry thoroughly. Do not use toxic products like Lysol or Pinesol. Allow at least 30 minutes to an hour to dry and ventilate. (If you can smell something when you stick your head in the cage, wait until you can no longer smell the cleaning solutions before putting the snake back in the cage.)

Blood Python Ventilation

Since bloods need high humidity, it is important to have a well ventilated cage. Screen (metal wire) mesh tops work well, and pose no immediate concerns to basking lamps which sit on top to be used as an additional heat source (although lamps are not needed for bloods).

Blood Python Substrate

Newspaper allows for easy clean up and it minimizes parasite outbreaks. Thought not visually appealing, it is by far the most easily maintained. As a drawback, it does not hold humidity well. Orchid bark chips and coconut chips will retain more humidity and be more visually appealing than newspaper, but any type of shavings will be more to clean, and give parasites places to thrive. Cypress mulch, paper towels, Astroturf, aspen bedding and paper bags also work as substrates. Do not use sand, dirt, gravel, sawdust or cedar chips. It’s highly recommended not to saturate the substrate with water, but misting it once to a couple of times a day is acceptable. A wet substrate will mostly likely lead to skin ailments. Mist the separate hide filled with moss for humidity. If the cage is cleaned every time there is a dropping, you’ll minimize parasite infestations and keep a healthier blood. Make a habit to change the water at least every time you change the substrate (at least once a week). Ideally, however, you should change the water every single day. If you use shavings for your substrate, it’s recommended to feed your reptile on a different surface to avoid ingestion. Additionally, feeding any snake in another location will help it distinguish between handling time and feeding time.

Blood Python Hides and Water Dishes

Bloods love to hide out in the dark. It is absolutely essential to provide a tight, snug hide for any sized blood, as well as a water bowl. Clay or plastic flower pot bottoms with a cut out in the front and or a hole at the top are ideal for both hides and water dishes. It’s usually a good idea to locate the covered hide near the heat source. If a blood wants to cool down, it can always get out, but you don’t want to make it choose between the hide and heat. (Personally, I’ve actually put the covered hide over half or a third of the heating pad, knowing that there is enough room in the hide for the snake to sit on top of or completely avoid the heat source.) As mentioned already, misting an open top plant base filled with sphagnum moss or cypress mulch will provide concentrated humidity and security (youngsters will more than likely burrow underneath the moss). (See Humidity.) The same sized plant base works well for the humidity hide as well as the covered (upside down) hide. The water dish can be the same size or bigger, as long as the entire snake can fit in it for soaking. Disinfect the water bowl weekly, and place it in the cage near the heat source to provide additional humidity. If you desire, offer a second covered hide located on the cooler end of the cage as well. The more stress you can eliminate for the blood to experience, the fewer headaches you’ll experience.

Blood Pythons Temperature, Heating and Lighting

Blood Pythons are not as forgiving to inaccurate temperatures or humidity as a Common Boa, for example. Day time temperatures should range from 80° to 92° (All temperatures are listed at Fahrenheit.). The basking spot should reach 92° at maximum, with a temperature gradient to approximately 80° at the opposite end of the vivarium. If an under the tank heater (uth) is used, then the basking spot should cover one third of the vivarium. Thermostats connected to a heating pad are helpful, but rarely accurate. A temperature gun (available for purchase at Radio Shack) is a cost effective, ideal tool for monitoring cage temperatures. Use a temp gun to make sure the heat source (if using a lamp) is not too hot, as they can cause burns as well. Monitor lamp height and wattage. Temps guns are absolutely essential for this. If you have a blood that only stays in its hide in increments because the lamp is directly over the hide, you may want to consider changing the wattage. Lamps at or over 100 watts should be monitored, as used sparingly, depending on cage height. Thermometers located at both ends of the cage are a must. It is essential to have a temperature gradient for most snakes. The temperature ranges will change with different snakes, but a gradient will allow the snake to thermo-regulate itself. An under the tank heater can be used in conjunction with a light for heating, if necessary, for the higher temperatures. Incandescent lights are not recommended unless absolutely necessary for heating because they reduce humidity levels more than other types of lighting. Ceramic heating elements (attached to a thermostat for regulation) (CHE) are great supplements for heat. Just as it is important to get day time temperatures correct, so is it important to make certain night time temps are correct. Night time temperatures may drop between 75° to 80°. Some studies have shown that snakes that receive too much constant temperature can suffer from heat stress, leading to a number of problems. Bloods do not need light, but a good 12 hour photoperiod with a light source is, in many cases, the most practical solution. Most of the time, 12 hours on and 12 hours off is sufficient.

Under the cage heating pads and heat tape are a good supplemental heat forms, and are sometimes used as the primary source of heat. The use of a thermostat attached to the UTH is recommended, to ensure that temperatures are accurate and over-heating does not occur.

The use of hot rocks or heat rocks is not recommended, as these have been found to be dangerous and can cause fatal burns. The only recommendation for the use of a hot rock is if the power supply is cut, making the rock a simple decoration! Learn more about the Dangers Of Heat Rocks here: Heat Rocks – Hidden Dangers

Blood Python Humidity

It is highly recommended to give a blood a separate hide for humidity other than its covered hide. Flower pot bottoms made of plastic, clay or deli dishes work well. If you do use a deli dish, make sure there are no sharp edges. Fill the dish or flower pot bottom with moist moss. Sphagnum moss is ideal, but not the only type you can use. Cypress mulch works well also. Misting the dish filled with moss every couple of days will ensure a nice, humid hide. The hide needs to be moist but not wet, as an over saturated box may lead to skin irritations like “belly rot”.

(Note: A big misconception regarding humidity is that not enough humidity will cause problems. Although this is true in some cases, too-high humidity can equally cause problems such as respiratory infections. If you hear wheezing from your snake, cage temperature and humidity are a good place to start tracing your steps back to probable causes, though as with any infection or health problem you should be cautious and seek veterinary advice/treatment.)

Humidity gauges located at each end of the cage are ideal, but at least one is required. In general, you may also consider mounting a thermometer/humidity gauge for the room, if you have several reptiles with similar needs in the same room. If it drops too low, simply fill a humidifier with water and run until the room humidity gets to the optimal range. 65% to 70% humidity is ideal for bloods, while the humidity should be increased to 85% to 90% when in shed. Water bowls inside the blood’s cage will add to the humidity, and an additional water bowl may be placed at the warm end of the enclosure to increase humidity further if required. Usually, correct temperatures and water bowl evaporation will ensure correct humidity, although misting the enclosure may be necessary.
