Types of Tarantulas and Their Difficulty to Keep | Venom, How to Choose Between Beginner-Friendly and Advanced Species

Many people might have the impression that tarantulas are "scary," but in reality, keeping them is relatively straightforward, and many individuals can be handled. The true appeal of tarantula keeping lies in things you can only enjoy with them—their vivid coloration, unique ecology, and the mysterious phenomenon of molting. This article explains everything from the basics of tarantula care to species-specific difficulty levels in a way that's easy to understand for first-time keepers.

Basic Information About Tarantulas and Their Venom

Tarantulas are a general term for large spiders primarily inhabiting tropical and subtropical regions of Africa, South America, and Asia, officially belonging to the superfamily "Theraphosoidea." Body length varies greatly by species, ranging from small species around 5cm when their legs are spread to the Goliath birdeater, which exceeds 30cm.

Lifespan Females are long-lived, and it's not uncommon for some species to live 20–30 years or more. Males are significantly shorter-lived than females, with most dying within 1–2 years after reaching maturity. If you want a long-term companion, it's wise to choose a female.

About Venom Most tarantulas have venom glands, but their toxicity to humans is very low, and the majority of species cause pain comparable to a wasp sting even if bitten. However, people with allergies may experience severe reactions, so if bitten, do not let your guard down and monitor the situation carefully.

Additionally, many New World tarantulas (from the Americas) have "urticating hairs" on their abdomen. When sensing danger, they flick these hairs with their hind legs, and if they come into contact with the eyes or skin, they cause intense itching and inflammation. After handling, always wash your hands and be careful not to touch your face.

Beginner-Friendly Species and Their Characteristics

The most important factor in choosing a tarantula is "difficulty of care." The golden rule for beginners is to start with a docile and hardy terrestrial species.

The table below compares the characteristics of major species (prices and body lengths are approximate).

For your first tarantula, a docile and hardy Chilean Rose or Mexican Red Knee is the standard choice.

Grammostola rosea (Chilean Rose, scientific name Grammostola rosea) The classic beginner species for tarantula keeping. Their movements are slow and they are very docile, with many individuals tolerating handling. They are tolerant of low temperatures and low humidity, making care simple. However, "periods of refusing food" lasting several months are not uncommon, so patience to observe without panic even during periods of not eating is necessary.

Brachypelma hamorii (Mexican Red Knee) A popular species with beautiful red and black contrast. Their slow movements make them easy to observe, and they provide high visual satisfaction. Due to export regulations under the Convention on International Trade in Endangered Species (CITES Appendix II), always confirm when purchasing that the individual is captive-bred (CB).

Lasiodora parahybana (Brazilian Salmon Pink) A large species reaching 25cm in body length as an adult, with striking visual impact. With a relatively docile temperament, they require humidity to be kept slightly higher, but are hardy and easy to care for, making them a beginner to intermediate species.

Species for Intermediate to Advanced Keepers

Poecilotheria Genus (Indian Ornamental, etc.) Arboreal tarantulas with beautiful geometric patterns. They move extremely fast with impressive agility to close distance instantly. As Old World species (from Asia and Africa), they lack urticating hairs but have relatively potent venom, and bites can result in pain and swelling lasting several days. It is best to avoid handling completely and keep them purely for viewing.

Lampropelma Genus (Cobalt Blue, etc.) Old World burrowing tarantulas distinguished by their vibrant blue-purple coloration. They require high humidity (80–90%) and deep substrate, making their care delicate. They are shy and spend much time burrowed underground, rarely showing themselves. The beauty of those rare moments of encounter is why they're popular with collectors, and they're an aspirational species for advanced keepers.

Basic Care Setup and Environmental Configuration

Choosing an Enclosure Use plastic containers or specialized reptile enclosures sized to fit the species. Crucially, the lid must balance both airtightness and ventilation. Tarantulas are escape artists, able to flee through even tiny gaps. Install mesh vents on the sides or top to prevent moisture buildup. As a guideline, adult enclosure floor area should be about 2–3 times the spider's body length.

Substrate Use coco husk, peat moss, leaf litter, or combinations thereof. As a guideline, substrate depth should be 1–2 times the spider's body length. Adjust moisture content to match each species' humidity requirements.

• Terrestrial/dry species (Chilean Rose, etc.): Substrate should be somewhat dry, but many prefer a "wet corner" where one area is kept moist
• Arboreal species (Poecilotheria, etc.): Install hides using driftwood or artificial plants, maintaining humidity at 70–80%
• Burrowing/high-humidity species (Cobalt Blue, etc.): Keep substrate at least 15cm deep and maintain constant moisture

Temperature Management Most species require 25–28°C. During winter, apply a panel heater to the enclosure's side and monitor temperature with a thermometer. Avoid bottom heating, as it poses a risk of the spider being unable to escape from already-hot areas. Temperatures exceeding 30°C can be lethal, so pay attention to summer management as well.

Feeding, Hydration, and Molt Management

Feeding Crickets (sized SS–LL to match), dubia roaches, and mealworms are the primary foods. Offer live insects 1–2 times per week. Appropriate prey size should be roughly equal to the tarantula's abdomen (opisthosoma) or slightly smaller.

Remove any uneaten live prey immediately. Injuries from prey insects biting recently-molted or anorexic tarantulas happen frequently. If a tarantula hasn't eaten 24 hours after feeding, remove the prey without exception.

Hydration For juveniles, misting one area of the substrate is effective. For adults, keep a small shallow water dish permanently available. Avoid containers that are too deep to prevent drowning; placing cork or stones inside to keep the dish shallow is also effective.

Precautions Before and After Molting Before molting, you'll see signs such as "ceasing to eat," "abdomen darkening," and "spinning silk to construct a web." Once confirmed, stop feeding and observe quietly. During molting, avoiding disturbance is the absolute priority. Moving the spider while its exoskeleton is still soft can result in lasting damage. After molting, it takes 1–2 weeks for the exoskeleton to fully harden; during this period, do not resume feeding and provide only water.

Conclusion

With proper species selection and basic environmental management, tarantulas are pets that even beginners can thoroughly enjoy. The ideal path is to begin with beginner species like the Chilean Rose or Mexican Red Knee, develop a feel for tarantula care, and then advance to intermediate to advanced species. Choosing a female allows you to build a long-term partnership spanning decades. We encourage you to experience firsthand the unique presence and mysterious ecology that tarantulas offer.
