The Chaco Golden is a terrestrial tarantula that is native to Paraguay. The females of this species live longer than the males, which is largely due to how the species breeds. They take quite a few years to grow, especially compared to other tarantulas. If you purchase a baby, it will be years before the spider grows into an adult.

However, most new owners will be surprised that they will take years to reach full size, where their adult coloration is prominent. They will make themselves busy by digging holes and moving their substrate around, two of their favorite things to do.

Purchasing a baby provides owners a chance to get to know their spider before its large enough to bite. Tarantulas that drag their abdomen on the ground typically arent healthy. Despite being quite large, Chaco Golden Knee Tarantulas are also extremely gentle.

They are a bit flashy in appearance, with the golden stripes on their legs and lighter-colored hairs covering their body. One of the best ways to determine the temperament of a tarantula is to check for bald spots on its back. Hold your tarantula close to the ground in case it decides to jump.

Because tarantulas spend their life on the ground, the floor space of the tank matters more than the height. An easy way to prevent this is to put your pets tank on a table and then cover the legs with a healthy layer of petroleum jelly. Organic potting soil, coconut fiber mulch, and other similar substrates are the best options.

You should never use wood shavings, as these contain chemicals and oils that can be dangerous to your tarantula. Do this by pouring a generous amount of boiling water on it and letting it sit for about 10 minutes. Hollowed bark and coconut shells are often suitable and add climbing spots for your tarantula as well.

Room temperature is fine for these spiders, so do not add extra heating pads. Tarantulas cannot sense heat well, so they may not move to a cooler spot if they get too hot. You can feed your tarantula different prey items, including crickets, mealworms, maggots, and roaches.

In this case, you need to flip your tarantula over gently and drop water directly onto its fangs.

Chaco golden knee tarantulas (Grammostola pulchripes) are 7-8 diameter, terrestrial tarantulas native to Paraguay and Argentina. They prefer to live in grasslands with a climate of dry winters and wet summers.

These should be gradually upgraded until they are large enough to be comfortable in an adult-sized enclosure no smaller than 20L x 10W x 18H, or a 15 gallon high tank. Alternatively, replace the screen with a sheet of acrylic with small holes drilled into it for ventilation.

Housing multiple tarantulas in the same terrarium is not recommended, and is likely to result in cannibalism if attempted. However, there is some evidence to suggest that tarantulas may benefit from UVB lighting when appropriately provided. If you want to provide UVB for your tarantula, the best bulb to use will be a compact coil Zoo Med Reptisun 5.0 26w , mounted horizontally in a reflective fixture.

Place this lamp on top of a mesh lid with holes large enough to prevent the spider from getting its feet caught, so you may want to wait to provide UVB lighting until the tarantula has grown large enough for an adult enclosure. UVB output decays with age, so the bulb must be replaced every 6 months to maintain performance. Chaco golden knee tarantulas are primarily insectivores , which means that they need to eat a variety of insects to get the right nutrition.

That being said, chaco golden knee tarantulas tend to tolerate human interaction fairly well.

– Tarantulas have hairs called urticating hairs on the sides and back of their abdomens. These hairs can be dropped or flung if the tarantula is under stress. Urticating hairs are itchy and can be irritating to the noses, mouths, and eyes of predators.

Description and behavior[edit]

The Chaco golden knee is a large tarantula, being able to reach between 7 and 8 inches in legspan (17.8-20.3 cm). Being a terrestrial tarantula, it has a heavy body. Mature males have longer legs and smaller bodies than females, and they possess tibial hooks or apophyses to hold back a female’s fangs during mating. Males also possess modified pedipalps to insert sperm into the female’s genital operculum. It exhibits a multitude of colors, with bright yellowish leg stripes, dark black “femurs”, and pink hairs all over its body. As with the rest of the genus

Natural habitat[edit]

The Chaco golden knee tarantulas are known to inhabit the grasslands of Argentina and Paraguay.

As a pet[edit]

The Chaco golden knee is a very calm and docile tarantula, which, along with its striking appearance and large size, makes it an attractive pet, especially for beginners. It frequently sits in plain view in captivity, and likes to shove substrate around, especially at young ages. Females can live for well over twenty years, while males only live for about five or six years. The tarantula must periodically molt its exoskeleton to grow larger, and it is vulnerable during this time. This can happen every few weeks for newborn spiderlings or every few years for large adults.The Chaco golden knee tends to be one of the more docile and calm species of tarantula and therefore makes an attractive first pet. The Chaco is an opportunistic burrowing terrestrial tarantula: they tend to burrow while younger and adopt a pre-existing hide as its home when it begins to mature. It is quite flashy in appearance, bearing long light-colored hairs all over its body and gold stripes on its legs, particularly at the “knees”. This is a good display species as it often sits in plain view. When it was first imported into the pet trade, it was thought to be a variant of the Pink zebra beauty species, but it is significantly larger and can easily be distinguished by the size difference, with the most notable comparative feature being the leg-span, though an experienced owner could distinguish the colouring.

Chaco Golden Knee Tarantula Overview

This species is one of the best options for beginner tarantula owners. They are sweet and calm, so they don’t require much experienced handling. They are quite hardy, so you aren’t going to kill them easily. They can put up with errors from their owner, especially while you are learning. This makes them one of the best starter tarantulas out there. If you’ve never owned a tarantula before, we recommend this one.These tarantulas are characterized by the yellow stripes on their knees, hence their name. The males live significantly shorter lifespans than the females. Compared to tarantulas in the same genus, they grow quite quickly. However, most new owners will be surprised that they will take years to reach full size, where their adult coloration is prominent.While most tarantulas don’t require much activity, these are extremely active. They will make themselves busy by digging holes and moving their substrate around, two of their favorite things to do.It is recommended that most owners purchase a spiderling first. It will not bite due to its smaller size. Instead, it will often be intimidated by the sheer size of the human hand. Purchasing a baby provides owners a chance to get to know their spider before it’s large enough to bite.The care needs for these tarantulas are simple. They don’t need much expert care and will generally thrive in most environments.

Typical Behavior & Temperament

Despite being quite large, Chaco Golden Knee Tarantulas are also extremely gentle. They are one of the most docile tarantulas around, which is exactly why they are often recommended for first-time owners. Females are particularly laidback and easy to handle. Males can be a bit aggressive, as their only motivation in life is to find a mate. Therefore, they may become somewhat destructive. If you’re new around tarantulas, we recommend a female.Its temperament can shift substantially as it ages, though. Also, it can be difficult to determine the sex of a spider when it is young. A male can easily be mistaken for a female if it is larger than normal. For this reason, don’t be surprised if your tarantula is a bit more aggressive than you’d otherwise like.

Appearance & Varieties

These tarantulas look like you’d expect. They are a bit flashy in appearance, with the golden stripes on their legs and lighter-colored hairs covering their body. Typically, their main color is brown and black.As larger tarantulas, they can reach up to 8.5”. Females are typically larger than males.

If it has bald spots, it has previously thrown hairs.

Keeping Your Chaco Golden Knee Tarantulas Healthy

If your tarantula’s enclosure is set up correctly, then it should stay healthy. The important thing to remember is that its substrate needs to be sprayed regularly. Often, you should only spray the half that your tarantula isn’t on. If you spray your tarantula, you will upset it. If the substrate gets dry, though, then the humidity in the tank can fall substantially.Any substrate with mold or mites should be changed immediately, even if it isn’t time to change it yet. Mold can grow directly on your tarantula, which can cause breathing problems.If you notice mites, you should remove the tarantula and inspect it to see if any mites are attached to it. Use a paper towel to remove these mites. Pay close attention to any areas where the mites can cling to, such as the legs and mouth of your tarantula.Tarantulas do not bleed red. Instead, they bleed a milky, semi-clear substance. They often won’t bleed profusely either, as it is more of an ooze. They do not clot like mammals, so any wound needs to be treated right away to prevent excessive bleeding. Wounds can be treated with a Q-tip and water-based glue. Liquid Band-Aid also works. Be sure not to use these substances extensively, though, as they can cause movement problems for your tarantula.Dehydration is a common problem, especially if heat pads are used. If its abdomen is wrinkled or deflated, the spider is dehydrated. In this case, you need to flip your tarantula over gently and drop water directly onto its fangs. You just need a few drops. Your tarantula should quickly regain its strength. Then, fix whatever issue caused your tarantula to become injured in the first place.

Breeding

It is generally not recommended to breed tarantulas unless you are a professional. Females will attempt to eat the male when they are done!Breeding is usually as simple as placing the male in the female’s habitat. They should start the courtship process. When they are done, the male must be rescued before he is eaten.

Do chaco golden knee tarantulas need UVB?

Chaco golden knee tarantulas are generally kept without UVB lighting, as they have proven to be capable of surviving without it, and considering that UVB wavelengths are blocked by glass and acrylic, installing the lamp can be tricky.However, there is some evidence to suggest that tarantulas may benefit from UVB lighting when appropriately provided. This paper speculates that wild tarantulas may get at least part of their vitamin D3 from UVB exposure, and this paper provides evidence of invertebrates being able to synthesize vitamin D3 from UVB.If you want to provide UVB for your tarantula, the best bulb to use will be a compact coil Zoo Med Reptisun 5.0 26w, mounted horizontally in a reflective fixture. Place this lamp on top of a mesh lid with holes large enough to prevent the spider from getting its feet caught, so you may want to wait to provide UVB lighting until the tarantula has grown large enough for an adult enclosure. UVB output decays with age, so the bulb must be replaced every 6 months to maintain performance.Lights should be on for 12 hours/day.

Best temperature for chaco golden knee tarantulas

Chaco golden knee tarantulas should be kept between 68-78°F. This is generally consistent with room temperature, but if you need additional heating, use a small heat mat stuck to the side of the enclosure and connected to a thermostat to maintain consistent temperature. Use a digital probe thermometer to keep track of enclosure temperatures.
