Is this tarantula suitable for beginners?

It's generally considered a species for experienced keepers, given how quick-moving and defensive it can be. We'd recommend building up tarantula-keeping experience before taking one on.

Females reach a maximum body length of about 8cm, making it a relatively compact tarantula.

How long do they live?

Females can live around 10 years, making this a long-lived species. Males, however, die roughly four months after their maturing molt, so females are the better choice for long-term keeping.

When does the blue coloring appear?

Juveniles are plain brown, and females start developing blue hairs at the base of their legs around the fifth molt. The blue comes from the hair's structure rather than pigment.

Is it safe to handle by hand?

Handling isn't recommended, as this species is fast-moving and quick to become defensive. It's best enjoyed by observing rather than handling.

Electric Blue Tarantula

The Electric Blue Tarantula is a fossorial species native to Thailand's mangrove forests, spending much of its life underground. Its body is a subdued brown, but around the fifth molt females develop a striking blue sheen on the underside of their legs that shifts with the light. This isn't pigment — the color comes from microscopic structures within the hairs themselves, which is why it doesn't fade over time. Quick-moving and somewhat high-strung, it needs a burrow-friendly setup, which is why it's generally regarded as a tarantula for experienced keepers rather than beginners.

About Electric Blue Tarantula

A fossorial tarantula from Thailand's mangrove forests, known for the vivid structural blue that develops on females' legs through successive molts. Best suited to experienced keepers.

7 things to know before welcoming a Electric Blue Tarantula

1Deep Substrate for Burrowing
Females reach a maximum body length of about 8cm — modest for a tarantula — but as a fossorial species it still needs substrate deep enough to dig a proper burrow. Adding a piece of cork bark can help it get started.
2Fast and Defensive Temperament
It's a skittish species, quick to flee or raise a threat posture when it feels threatened. As an Old World tarantula its bite is considered relatively potent, so it's best kept without unnecessary disturbance.
3Blue Hairs Develop Through Molts
Juveniles start out plain brown, and females begin developing blue hairs at the base of their legs around the fifth molt. Watching the color deepen with each subsequent molt is part of the appeal.
4Balancing Humidity and Ventilation
Coming from mangrove forest habitat, it needs a careful balance of substrate moisture and ventilation. Too much moisture invites mold and substrate breakdown, while too little can lead to molting problems.
5Feed in Moderation
Feeding live insects like crickets a few times a month is generally enough. When it's holed up in its burrow, there's no need to force feeding — just wait until it comes out on its own.
6Lifespan Differs by Sex
Females are long-lived, typically around 10 years, while males die roughly four months after their maturing molt. If you want to keep one for the long term, a female is the better choice.
7Prepare an Enclosure and Hideout First
Before bringing one home, prepare an enclosure that can hold deep substrate along with heating and humidity control. Since it likes to hide, adding cork bark or another shelter will help it settle in.
