About: Brachypelma auratum, commonly known as the Mexican Flame Knee, is a stunning and highly sought-after species in the tarantula hobby. It is easy to see why—this species features a rich black base coloration accented by vivid reddish-orange striping on the knees, creating a striking and elegant appearance. Spiderlings and juveniles are often quite active and are known to construct intricate burrows, making them fascinating to observe.

This species is also an enthusiastic feeder, typically displaying a strong feeding response and rarely refusing meals. Adults tend to be more sedentary, as is typical for terrestrial Brachypelma species, but they still make an excellent display animal. B. auratum is considered a great choice for beginners due to its generally calm temperament, slow growth rate, and rarity of defensive behaviors such as threat posing.

Native to Mexico, this terrestrial species thrives in a dry to semi-arid setup with adequate ventilation and a deep substrate for burrowing. Like other Brachypelma species, it is long-lived, with females potentially living 20 years or more when properly cared for. Overall, Brachypelma auratum is a hardy, visually impressive tarantula that makes a rewarding addition to any collection.
