The Mexican Redknee Tarantula is perhaps one of the most famous of all tarantulas. Used in movies, commercials, magazines and even newspapers due to its amazing colors. They originate from south-western Mexico and have become a very common New World tarantula kept as a pet. Once thought to be endangered its numbers have grown quite a bit, especially due to how easily these animals breed in captivity. Now they are one of the most sought after species and surely an easy find at any exotic expo throughout the world.

Being a native of the hills of the south-west Mexico these animals love the dryness the key is to keep your substrate relatively dry to replicate their arid environment in the wild. Make sure to at least refill your tarantula’s water dish once a week with fresh clean water and simply overfill it to dampen just a slight patch of your substrate. This should create adequate humidity for your tarantula. As always we would recommend a terrarium anywhere between 5 to 10 gallons depending on your tarantula’s size with about 2 to 3 inches of it filled with the substrate of your choice such as eco-earth. This species has been known to burrow so make sure to also add something it can use as housing such as half a florwepot into the substrate. You can add decorations such as plants to your enclosure but your redknee will not care for it.



Your Mexican Redknee Tarantula usually eats crickets and meal-worms but when big can even eat a cockroach or two. A full grown redknee will eat 1 or 2 large crickets a week but can sometimes go as far at 6 months without wanting to eat. As long as you see its abdomen remaining big in size you should not worry about it not eating. They are slow moving and most of the time will either strike fast as soon as you put a cricket in its enclosure or will not do anything at all. Do not leave the insect in the enclosure if you notice it not being eaten within 24 hours.



Though extremely docile the redknee does have some defenses when threatened. It’s a new world spider and therefor does come equipped with urticating hairs which it will flick off its abdomen should it feel intimidated. Should they feel vulnerable they also to rear up and show their fangs. So as always test the waters before trying to handle them to see what mood they are in. A simple approach would be to gently nudge it from behind with an elongated Q-Tip before trying to pick it up.


This tarantula is rather sluggish which makes it very easy to handle.  The Mexican Redknee tarantula is quite slow at growing. Mine grew from a 1 inch sling (spider-ling) to about 5 inches over the course of 5 years. The males will live a good 5 to 6 years while females can live upwards of 30 years with ease.  All in all we would recommend this as a first time beginner tarantula due to its low maintenance, being very submissive and also easy to handle.
