Colombian Laser Spider (Latin name: Xenesthis immanis) is native to southern Colombia and Peru and is one of the most classic and visually appealing species among pet bird-eating spiders. Adult spiders can reach a body length of 23-25+ centimeters, covered with black velvety hair and shiny pink long hairs on the abdomen. The most distinctive and shiny feature is their purple and laser-patterned carapace. Adult males are the most colorful, showing a purple color similar to Haitian coffee bird-eaters.

Colombian Laser Spider: also known as Colombian Laser, is a reptile belonging to the spider order, bird-eating spider family, and Xenesthis genus. It is native to the tropical rainforests of southern Colombia to Peru in South America. Despite its wide distribution, the export quantity is very small. It has a slow growth rate and a long lifespan, making it one of the longest-lived pet bird-eating spider species. The color that appears after each molt is amazing. It shares a nest with a local species of toad. Researchers speculate that this toad avoids being preyed on by spiders by relying on toxins on its body and can also eat insects that produce disturbances but are too small to be caught by spiders. Adult female spiders can also share their nests with older offspring.
The Colombian Laser Spider (Latin name: Xenesthis immanis) is recommended for enthusiasts of pet bird-eating spiders. Its entire body is covered with velvety black hairs, and its abdomen has shiny and prominent pink hairs. Its purple color and shiny, laser-patterned dorsal exoskeleton are the most distinctive features. The colors of adult males are the most dazzling. It is difficult to raise and has a strong aggressiveness, making it a breed for advanced keepers.
1. Emaciation
When you find that the spider's body becomes dull, and the skin starts to become dry and yellow, it is likely to be suffering from emaciation. This condition is usually caused by the spider not eating well, leading to malnutrition.
2. Enteritis
Contrary to emaciation, this condition is caused by overeating. If the owner keeps feeding the spider constantly, or if the food temperature is too low during feeding, it can cause bloating and abdominal pain, eventually leading to enteritis.
3. Hemiplegia
Spiders do not have high environmental requirements, but when the temperature is too high, especially in summer, with high humidity, if the spider's cage is far from the ventilation, it can cause the spider to experience heatstroke-like symptoms, resulting in paralysis and hemiplegia.
4. Constipation
Constipation is mostly caused by not drinking water. Besides eating, spiders also need water. If the owner only feeds the spider but does not provide water, the moisture in the food is not enough to meet the spider's water needs.
5. Black rot disease
Loss of appetite, lethargy, and the appearance of black, ulcerative lesions on the abdomen are signs of black rot disease in spiders. The cause of this condition is stale water and food. If spiders eat food contaminated with bacteria, they can contract black rot disease, which can be fatal.
6. Mold disease
Especially in the southern region, in hot and humid weather, spider's bodies are prone to bacterial infestation. The spider's joints become increasingly stiff, and the body becomes increasingly damp, providing an ideal environment for bacteria to survive and multiply, resulting in the formation of mold spots on the spider's body.
7. Parasitic infections
Parasitic infection is probably the most disgusting disease for spiders. If it's small parasites, it's relatively okay, but those persistent parasites crawling on the spider's body are extremely disgusting. Besides affecting the spider's rest, they may also carry other viruses, causing multiple infections and threatening the spider's life.
1. Temperature
Temperature is best controlled between 25 and 30 degrees Celsius, and the temperature difference between day and night should not be too large. In summer, pay attention to cooling and preventing heatstroke, and in winter, pay attention to warming and keeping warm to ensure the healthy living of spiderlings.
2. Humidity
Moderate humidity should be maintained at around 65%. Low humidity can easily lead to dehydration and eventually emaciation and death of spiderlings. If the humidity is too high, spiderlings are prone to edema and death due to water retention or fungal infections.
3. Ventilation
Good ventilation can make spiderlings stronger, reduce diseases, and safely undergo molting. Air pollution, dampness, and stuffiness are the main causes of spiderling mortality.
4. Food
Feeding small animals such as fruit flies and small earthworms is the main diet for spiderlings. Blood can also be fed (without adding salt). If conditions allow, artificial formulated feed can be used. A common formula is: 50% egg yolk, 20% honey, 20% milk, 4% vitamin additives, and 3% brewer's yeast. After mixing, place it on a dish or sponge for feeding.
5. Lighting
First and foremost, lighting should be adequate. If conditions permit, spiderlings can be taken outside to receive light. (Spiders do not like light, so there should be shaded areas to ensure their safety). Windows should be opened frequently, but direct sunlight should be avoided.
