Other common names: Blue Tarantula
Scientific name: Haplopelma lividum
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.

Ooh, the cobalt blue. I have never seen an angrier spider than my OBTs, but this T manages to beat them. It will rear the instant their enclosure is even slightly moved or began to be opened, even for feeding or misting. I would NOT recommend this T for beginners, or even somewhat seasoned keepers. It is definitely for expert keepers, and even then, I don't know why anyone would want to keep this little jerk other than its absolutely stunning blue coloring, unless you for some reason really like aggressive species. Aside from their easily upset demeanor, they're not the easiest to care for either. They are picky about feeding, and very touchy to their climate and atmosphere. Keep at your own risk. .

The Cobalt Blue: Good tarantulas?
I've been a keeper of Tarantulas for just over 3 years now, it's one of those "addictive" hobbies as there are so many species but the Cobalt Blue is by far one of the most striking to look at and watch.
The pearlescent blue effect, if caught in the right light is breath taking and photographs wonderfully.
Many wikis say that the Cobalt is a highly defensive Taranutla but my experience with Midnight is nothing like it, she is very docile though I do not handle ANY of my Tarantulas, I don't believe in it but when opening her tank she doesn't threat pose or kick, just sits there.
That being said they are lightning fast and when offered prey will take it down like a high-speed train.
Cobalt Blues are a great pet for an advanced keeper, they don't want for much as long as you provide a nice deep habitat for them to make a burrow in.
I very much enjoy looking at her and taking in her gorgeous colouration..

Beautiful but beware!
My experience with the beautiful Cobalt Blue Tarantula was not a good one. I housed him in a glass terrarium with a screw-on, metal mesh cap. The spider was constantly trying to find a way out through the cap. He would pick at it for hours at a time. I foolishly thought he could never get out.
The Cobalt Blue was exciting to watch. He was high-energy and usually was out and about.
There are slow-moving tarantulas, and very quick tarantulas. The Cobalt Blue fell under the category of very quick, which made it difficult to feed him. When tossing crickets into the terrarium, it was always a frightful struggle to get the cap screwed back on before he dove for the exit.
As well, there are mild-mannered tarantulas, and fierce ones. The Cobalt was fierce. When we would walk past his glass enclosure he would attack the side of the glass with an audible click from his fangs.
One morning, when walking past his enclosure, I stopped in my tracks because I didn't hear his click. I looked closer and saw that he had somehow chewed his way out of the metal mesh cap. His terrarium was empty and he was loose somewhere in the house.
I had heard that the Cobalt Blue was one of the more venomous varieties of tarantula. Deciding to fumigate the entire house I sat down to pull on my boots and go out to buy a dozen bug bombs. After struggling for a half a minute to get my boot on, and not being able to figure out why it wouldn't fit, I suddenly realized something was in my boot that kept my foot from being able to fit!
With a scream, I threw my boot out the front door and into the driveway. Knowing he was in there I turned over a garbage can on top of the boot and left it that way until my husband came home.
I'll never know what he did, but he said that he took care of it.
I do not recommend the Cobalt Blue tarantula for a house pet or casual handler. They would however be good to keep for someone who studies tarantulas and would enjoy watching their day to day activities..
