Greenbottle Blue Tarantula (Chromatopelma cyaneopubescens) Care Sheet

The greenbottle blue tarantula - often known simply as the GBB - is one of the most colorful pet tarantulas available in the trade. Hailing from Venezuela, this care sheet reveals exactly how to keep greenbottle blue tarantulas as pets. The Greenbottle Blue tarantula is one of the most stunning tarantulas in the world.

While “blue” tarantulas are always popular in the hobby, I would argue that the green bottle blue is one of the very best. It manages to combine stunning colors with ease of care and docility that make it a perfect pet.

Growing to around 5″ in legspan as adults these aren’t the largest of tarantulas, but this is definitely made up for by their orange rumps, metallic green carapace and almost unbelievable metallic blue legs.

Viewed in natural sunlight (where the blues really come into their own) I would argue that the Green bottle blue tarantula truly is one of the very best-looking tarantulas of all.

Wild Greenbottle Blue Tarantula Environment

It is well-known that this tarantula hails from Venezuela in South America. As a result of this many keepers in the past have assumed that green bottle blue tarantulas require a very humid tropical environment but this isn’t necessarily the case.

Indeed, as many keepers have found to their detriment, an overly moist environment can lead to significant problems.

In reality the GBB comes for a small peninsula on Venezuela, located in the Caribbean Sea. Known as “Paraguana” the climate here is anything but humid.

The WWF reports that the area is surprisingly arid, representing largely dry scrubland. Temperatures vary widely, reaching up to 50’C in exposed areas, though with significant drops in the shade and/or blow ground.

The green bottle blue tarantula itself is generally to be found here, burrowing through the sandy soil beneath bushes and rocks. The GBB produces copious amounts of web in order to prevent their burrows from collapsing – and this webbing is also seen in captivity.

Broadly speaking these are sturdy spiders, which have evolved to live in a relatively harsh environment. This makes for a very forgiving species in captivity so long as it is not kept too moist.

Greenbottle Blue Caging

Some disagreements exist in the tarantula hobby as to whether the greenbottle blue is terrestrial or arboreal as it seems these adaptable spiders will adjust to almost any captive conditions.

Studies in the wild suggest these are almost exclusively terrestrial, so we would suggest attempting to replicate this in captivity.

While these aren’t the largest tarantulas in the hobby, they are far more active than many species.

This, combined with their excessive webbing, means that a decent-sized cage is required if you are to observe all the fascinating behaviour these spiders exhibit.

At a very minimum I would suggest a cage measuring 12″x8″ but larger is likely to be better. Personally I have had good results with Exo Terras and now use them almost exclusively for my small collection of adult specimens.

When selecting a suitable Green Bottle Blue cage one of the most critical aspects is that it should have appropriate ventilation. This helps to avoid the potentially harmful build-up of moisture which can have a detrimental effect on your spider.

Note that green bottle blue tarantulas produce copious amounts of web, and you will be able to observe the fascinating process of a perfectly-landscaped cage slowly being filled with thick white silk.

This adds further to the benefits of larger cages, as in overly-small cages the entire inner surface may become covered in web, thus obstructing your view of your new pet.

Heating

While the natural environment of the green bottle blue can get very warm indeed, as stated previously these spiders tend to burrow away and so miss out on the worst of the heat.

As a result typical “tarantula temperatures” of around 25’C are perfectly appropriate for this species. Due to the fact that they tend to burrow to avoid heat, underfloor heating is unlikely to be the most appropriate form of heating, and instead a mat pad can be attached to one side of the cage.

In this way a thermal gradient will be created, and the spider will be able to make its lair in the area with the most appropriate temperature.

For individual cages I like to use this size with my Exo Terras; for larger number of cages I use heat strips, which can warm a larger number of cages while still only utilizing a single plug.

Water and Humidity

The Green Bottle Blue tarantula hails from semi-arid grassland areas so requires a lower humidity than perhaps many other commonly-kept species. Think more of the Aphonopelma and Brachypelma species from the deserts of Mexico and North America.

While humidity will still be required for moulting purposes, it is important that the tank isn’t “saturated”. Just an occasional spraying is likely to be more than enough when your spider isn’t moulting, with plenty of time allowed between sprays for the tank to dry out properly.

As with all tarantulas, a shallow water dish should be provided at all times. Deeper dishes should ideally be avoided, in order to prevent the risk of drowning.

In the case of the green bottle blue it is also wise to try and place the water bowl at the opposite end of the tank to the hide. As this species produces so much web, placing the water bowl away from your pet’s lair means less disturbance of the web when you carry out the necessary daily water changes.

Cage Furnishings

This species is pretty undemanding in captivity and requires no special equipment or setup.

As this is a partly burrowing species, it can be wise to add a decent depth of substrate which allows you pet the benefit of being able to rearrange it to their liking.

Good options are coir or potting compost, and this should be provided to a depth of several inches.

Besides this it is wise to add a number of potential hides for your pet, in order to allow them some privacy. Suitable options include curved pieces of cork bark and plant pots. As this species produces so much webbing, my preference is for the latter.

I place two or more plastic flower pots on their side and partially bury them in the substrate. This way not only can the spider choose between multiple hides but cleaning these plastic pots tends to be much easier than a rough piece of bark.

Feeding Green Bottle Tarantulas

Chromatopelma cyaneopubescens is a voracious feeder and quite a fast-growing species. You’re unlikely to have to worry about this species going off its food apart from around the time of a moult.

Indeed, this is one of my favorite species to feed as their appetite is almost never-ending and with their lightning-fast reflexes you are almost guaranteed a great show when throwing in some live insects.

Green bottle blues will take all the normal insect prey, such as crickets and mealworms, up to quite a decent size. Feed your pet freely and see just how rapidly they grow!

Handling

How to keep the green bottle blue tarantula (Chromatoplema cyaneopubescens) in captivity.

Green Bottle Blue tarantulas are known for their docile attitudes, and very rarely attempt to bite or display aggression to their keepers. That said, this species is quite skittish and when surprised or scared can move with great speed.

As a result, while the chances of being bitten are minimal, most keepers choose not the handle this species. It would be all too easy to drop such a spider if it makes a break for freedom, which can result in a ruptured abdomen and consequently death.

Generally speaking it is safest for the spider to gently coax it into a plastic container if it needs to be removed before adding a close-fitting lid to prevent escape. Once the cage has been cleaned the spider can then be allowed out of the container.
