Other common names: Blue Tarantula

Scientific name: Haplopelma lividum

The basics:
The Cobalt Blue Tarantula is a burrowing tarantula from tropical forests of Myanmar, Thailand, Laos, Cambodia, and Vietnam.

Haplopelma lividum is prized in the pet trade because of its wonderful iridescent blue coloration, which is present in both males and females. However, the Cobalt Blue Tarantula is also known to be a fast, and very defensive tarantula species, and is recommended only as a display species for intermediate or advanced owners.

Appearance / health:
The Cobalt Blue Tarantula mainly looks black, but if in the right light and with a closer look this species shows a bright electric blue color on its legs.. As adults, they average about 4 or 5 inches in diameter. The Cobalt Blue's abdomen is dark gray or brown with a stripe pattern, while the rest of the body is light brown.

Behavior / temperament:
These tarantulas are very popular, but aren't recommended for beginners. Cobalt Blue Tarantulas are extremely aggressive, fast, and possess a painful, dangerous bite. Even the spiderlings of this species have been known to be overly nervous and show aggression.

Cobalt Blue Tarantulas should be kept in a large tank, but many people use a 5-10 gallon tank with no worries. Floor space is more important as they are a terrestrial burrowing species.

High humidity and temperatures are a must. Humidity levels should be around 75-85% and temps should stay around 80-90F. Provide a large shallow open water dish to help keep humidity up as well as misting the cage. Deep substrate is also a must, again these are a burrowing species. 5-8 inches of peat moss and vermiculite will do. These tarantulas are commonly referred to as having a “pet hole” because they stay in their burrow most of the time. If you want to see it more, create a preformed burrow between the glass and the substrate.

Spiderlings eat pinhead crickets, fruit flies, and other small insects. Adults eat crickets, and other large insects such as cockroaches and grasshoppers.

Adult males should be carefully introduced into the female’s enclosure after he has produced a sperm web. The female should be very well-fed before any introductions. Females may attack and eat the males before any mating can occur. So, if both male and female are well-fed, breeding success is more likely.
