Mexican redknee tarantula
BeginnerBrachypelma hamorii
Brachypelma hamorii is a ground-dwelling tarantula native to western Mexico. It is black in color and has vivid orange-red markings on its leg joints. It is one of the most well-known tarantulas. Many specimens kept as “Brachypelma smithi” in the hobby are actually this species, as the two were not clearly distinguished until 2017. The species grows slowly and is hardy. Females can live for over 20 years. It is tolerant of minor husbandry mistakes and has no strict environmental requirements, making it a good choice as a first tarantula. Keepers should be patient with its slow growth. Additionally, a certificate of origin is required because the species is protected under conservation laws.

Nutrition & care
- Feeding notes
- Crickets, grasshoppers, cockroaches, or locusts—no larger than the animal itself. Adults are fed 1-2 live prey items every 1-2 weeks. Juveniles are fed 1-2 times a week.
- Molting notes
- Before molting, the spider stops eating, and its abdomen darkens. It must not be disturbed during molting. After molting, depending on its size, it needs a 1-2 week break from feeding. Live prey must be removed.
