By The Black Tree Monitor (Varanus beccarii) is a fascinating and intelligent arboreal lizard native to the Aru Islands off the coast of New Guinea. Known for their sleek black appearance and remarkable climbing abilities, these reptiles have become increasingly popular pets among reptile enthusiasts. However, proper care and feeding are essential for ensuring a healthy and happy Black Tree Monitor. In this comprehensive guide, we’ll discuss everything you need to know about Black Tree Monitor feeding, along with additional information on their overall care and housing requirements.

1. Understanding the Black Tree Monitor’s Natural Diet
In the wild, Black Tree Monitors primarily consume a diet consisting of insects and other small invertebrates. They have been known to eat small lizards, birds, and even small mammals on occasion. As opportunistic feeders, these monitors will consume whatever prey is available to them in their natural habitat. Therefore, it’s crucial to replicate this diverse diet when feeding your Black Tree Monitor in captivity.
A. Insects and Invertebrates
The majority of a Black Tree Monitor’s diet should consist of insects and invertebrates, such as:
- Crickets
- Dubia roaches
- Mealworms
- Waxworms
- Silkworms
- Hornworms
- Locusts
- Grasshoppers
These insects provide essential nutrients, such as proteins, fats, vitamins, and minerals, necessary for the monitor’s growth and overall health. It’s vital to offer your Black Tree Monitor a variety of insects to prevent nutritional deficiencies and boredom.
B. Small Vertebrates
Occasionally, Black Tree Monitors may consume small vertebrates in the wild. In captivity, you may offer them:
- Small lizards
- Pinky mice or fuzzies (sparingly)
- Small fish (like feeder guppies)
It’s important to note that feeding small vertebrates should be done infrequently, as they are higher in fat and may lead to obesity if fed too often.
2. Feeding Frequency and Portion Sizes
Black Tree Monitors should be fed daily, especially when they are young and growing. As they reach adulthood, you may reduce the feeding frequency to every other day if they maintain a healthy body weight. It’s essential to monitor their weight and adjust feeding accordingly to prevent obesity.
There is no set portion size for feeding your Black Tree Monitor, as their appetite may vary depending on factors such as age, size, and activity level. Offer enough food to satisfy their hunger without overfeeding them. They should consume all offered food within 15-20 minutes. If they leave food behind, reduce the portion size at the next feeding.
3. Gut-Loading and Dusting Insects
To ensure your Black Tree Monitor receives adequate nutrition, it’s crucial to gut-load and dust the insects you feed them. Gut-loading is the process of feeding insects a nutritious diet before offering them to your monitor. This ensures that the insects are full of essential nutrients that will be passed on to your reptile.
Dusting insects involves lightly coating them with a calcium or multivitamin supplement powder before feeding them to your monitor. This helps to prevent potential health issues, such as metabolic bone disease, caused by calcium and vitamin D3 deficiencies.
A. Gut-Loading Insects
Feed insects a high-quality diet, such as:
- Fresh fruits and vegetables
- High-quality insect gut-load products
Ensure that the insects are well-fed for 24-48 hours before offering them to your Black Tree Monitor.
B. Dusting Insects
Dust insects with calcium and vitamin supplements, such as:
- Calcium with or without vitamin D3
- Multivitamin powder
Dust insects at every feeding for juveniles and at least 2-3 times a week for adults.
4. Providing Fresh Water
In addition to a balanced diet, it’s essential to provide your Black Tree Monitor with fresh, clean water daily. Use a shallow water dish that is large enough for your monitor to drink from and soak in. Change the water daily and clean the dish weekly to prevent bacterial growth.
5. Monitoring and Adjusting Your Black Tree Monitor’s Diet
Regularly monitor your Black Tree Monitor’s weight, body condition, and overall health to ensure they are receiving proper nutrition. If you notice any signs of illness, such as lethargy, weight loss, or poor shedding, consult with a reptile veterinarian to determine if a dietary adjustment is necessary.
A. Signs of a Healthy Diet
A well-fed Black Tree Monitor should display the following characteristics:
- Bright, alert eyes
- A healthy appetite
- Regular shedding
- Steady weight gain (for juveniles) or maintenance of a healthy weight (for adults)
- Normal feces
B. Signs of an Unhealthy Diet
If your Black Tree Monitor displays any of the following signs, consult with a reptile veterinarian to discuss potential dietary adjustments:
- Lethargy
- Weight loss
- Poor shedding
- Refusal to eat
- Abnormal feces
6. Common Health Issues
Black Tree Monitors are generally hardy animals, but they can still experience health issues if not cared for properly. Some common health problems include:
- Dehydration
- Stress
- Dysecdysis (improper shedding)
- Metabolic bone disease
Consult with a reptile veterinarian if you suspect your Black Tree Monitor is experiencing any health issues.
7. Breeding Black Tree Monitors
Breeding Black Tree Monitors in captivity can be a challenging but rewarding experience. It requires careful attention to environmental conditions, such as temperature and humidity, as well as proper pair bonding and nesting areas for the female to lay her eggs. If you’re interested in breeding Black Tree Monitors, consult with experienced breeders or a reptile veterinarian for guidance.
In conclusion, Black Tree Monitor feeding is an essential aspect of their overall care. By providing a diverse diet of insects, occasional small vertebrates, and proper supplementation, you can ensure your monitor receives the necessary nutrients for optimal health and growth. Additionally, maintaining proper housing, lighting, temperature, and humidity conditions will contribute to your Black Tree Monitor’s well-being, making them a fascinating and rewarding pet for reptile enthusiasts.
