Cobalt blue tarantulas are enchanting creatures. From afar they look like ordinary black tarantulas but once you get close, you will notice the dark blue color with a metallic iridescence.

These tarantulas are considered intermediate-level pets, meaning they should be owned and handled by owners who have previous experience with arachnids. You might be drawn to it because of its color, but remember, keeping a cobalt blue tarantula is a responsibility. You do not have to observe it 24/7 but you need to make sure it stays healthy.

Basic Appearance of Cobalt Blue Tarantula

The cobalt blue tarantula is referred to as the Haplopelma lividum. It is a very rare species and belongs to the Theraphosidae family. The spider’s venom is not considered dangerous or fatal, but the bite can be extremely painful. This is why you have to be very careful.

The spider has an aggressive nature and can bite if it feels threatened. Therefore only experienced people should handle it.

The average length of a cobalt blue is about six inches. In the wild, they can grow up to nine inches. The leg span of an average cobalt blue can be about five inches. The male tarantulas grow very fast and almost reach their maximum size in their first year. Males can live up to 10 to 12 years, but females can live up to 20 to 24 years.

However, their growth depends a lot on what they eat on a daily basis. In the wild, they can hunt and manage on their own, but when they are in captivity, you need to make sure it receives a balanced and nutritious diet.

How to Ensure the Perfect Diet for Cobalt Blue Tarantulas

Here is a list of things you need to consider to make sure your eight-legged friend lives a healthy life:

1. Know What Type of Food It Prefers

Cobalt blue tarantulas are born carnivores, meaning it enjoys eating insects. Its diet should contain mealworms, wax worms, king worms, silkworms, dubia roaches, and crickets. Other delicacies include beetles, baby mice, and cockroaches. 

Tarantulas are predatory animals and the cobalt blue is no exception. Hence, it prefers live insects and animals to feed on. Live prey triggers its predatory senses and makes the meal more appetizing. It will often ignore the food if it’s dead or not moving.

Adult spiders can eat large crickets and other fully grown insects. Adult crickets have a hard exterior so avoid them when feeding your spiderlings. Instead, feed them smaller insects such as pinhead crickets. 

Some people think tarantulas can eat small fruits and berries. Well, they can indeed “eat” them but can not digest it properly. While some tarantulas may not have issues eating fruits, others may suffer from digestive problems. So, it is best to stick with an insect diet.

2. Gut-feed the Staple Insects

Insects are usually packed with nutrition but most insects have only one or two types of nutritional elements. For instance, crickets are a good source of minerals, vitamins, and fiber but lack calcium.

To make sure your spider gets all types of nutrition in the right amount, you have to gut-feed the insects.

Gut-feeding or gut-loading is the process of feeding live insects to make them a more nutritious meal for your pet. You can do this with crickets, super worms, mealworms, and other common insects.

3. Maintain a Feeding Schedule

The best part about this spider is that you do not have to feed it every day. Feeding it once or twice a week will be enough to ensure proper growth and development.

As for the spiderlings, feed them every two days. This is the stage when they need the most amount of nutrition which is why they need to be fed often.

Matured tarantulas can survive two months without feeding. Cobalt blue tarantulas are natural burrowers and spend most of their time underground. If you notice your spider is not eating and is staying hidden in its burrow, do not worry. It will come up and munch on its meal as soon as it gets hungry.

Tarantulas also like to fast so sometimes it might skip a meal or two.

4. Provide a Source of Water

Tarantulas do not need to drink a lot of water and their primary source of water is the insects they eat. Insects like hornworms have a high water content in their body, which is usually enough for the spider.

However, cobalt blue tarantulas are native to Thailand and are accustomed to a more tropical environment. Therefore, they need more water than other types of spiders. 

To be on the safe side, keep a water dish in the enclosure and refill it with fresh water every day.

5. No Need to Feed When Molting 

The hard exoskeleton of cobalt blue tarantulas protects their internal organs. The spider grows by changing this exoskeleton and forming a new one through the process called molting.

The spiders are at their weakest and most vulnerable stage when molting. Do not feed your cobalt blue when it is molting because its organs will be exposed and a live insect may attack it and harm it.

Their digestive system is also very weak at that stage so it is best to wait for a few weeks after they have molted. Spiders can survive a long time without food so there is nothing to worry about.

After 2-3 weeks of molting, you can resume your old feeding schedule.

6. Keep the Enclosure Clean

Your spider will eat the food quickly and return to its burrow. They will leave the leftovers behind. Be sure to clean its enclosure and remove the leftovers. Do not mix dead insects with live ones or it will cause health risks.

Feed your tarantula store-bought insects only. Insects found outside may contain pesticides that can be deadly for the spider.

Final Thoughts

Tarantulas can live a healthy life if you provide a balanced diet. Their dietary needs are easy to fulfil and are cheap compared to a lot of other pets. If you are experienced in owning exotic pets, a cobalt blue tarantula can be the perfect next member.
