🕷️ Colombian Blue Dwarf Tarantula Care Guide
Introduction
The Colombian Blue Dwarf Tarantula (Cyriocosmus elegans) is a small yet striking species native to the tropical regions of South America. Known for its iridescent blue legs, orange heart-shaped marking, and tiny size, this species has become a favorite among dwarf tarantula enthusiasts.
Despite being one of the smallest tarantulas in the hobby, the C. elegans displays all the fascinating behaviors of larger species — from intricate burrow building to enthusiastic feeding responses. It’s an excellent choice for keepers who appreciate vibrant coloration and manageable care requirements.
🌎 Natural Habitat
Native to Colombia and Venezuela, the Cyriocosmus elegans inhabits humid tropical forests where it constructs silk-lined burrows in leaf litter and soft soil. The climate in these areas is warm and moderately humid year-round.
In captivity, this species thrives in a well-ventilated enclosure with deep, moist substrate to encourage burrowing behavior.
🏡 Enclosure Setup
Due to its small size, the Colombian Blue Dwarf doesn’t require much space, but it does appreciate complexity in its environment.
Recommended enclosure size:
- Juveniles: 10 × 10 × 10 cm (4 × 4 × 4 in)
- Adults: 20 × 20 × 20 cm (8 × 8 × 8 in)
Setup tips:
- Substrate: 5–8 cm (2–3 in) of moist coco fibre or topsoil.
- Hide: Provide cork bark pieces, moss, or leaf litter for cover.
- Water: Include a small water dish or lightly mist the enclosure.
- Ventilation: Excellent airflow is key — mold and stale air can be harmful.
This species will often construct silk tunnels or a small burrow entrance surrounded by webbing — a sure sign it’s comfortable in its home.
🌡️ Temperature & Humidity
Maintain a temperature of 24–27 °C (75–81 °F) and a relative humidity of 70–80 %. Mist lightly every few days to keep part of the substrate damp, but avoid waterlogging.
A small enclosure makes it easier to maintain consistent warmth and humidity without overdoing it.
🍴 Feeding
Although small, the Colombian Blue Dwarf Tarantula has a voracious appetite. Feed appropriately sized prey such as:
- Pinhead or small crickets
- Roach nymphs
- Flightless fruit flies (for spiderlings)
Feed juveniles 2–3 times per week and adults every 7–10 days. Always remove uneaten prey within 24 hours, especially before a molt.
⚖️ Growth & Molting
C. elegans grows fairly quickly for a dwarf species, reaching maturity in around 2–3 years. Before molting, it may seal off its burrow or refuse food — a clear sign to reduce disturbance.
After a molt, wait at least a week before feeding to allow its new exoskeleton to harden.
⚠️ Temperament & Handling
This species is fast and shy, but not aggressive. It will retreat into its burrow when threatened rather than displaying defensive behavior. Handling is not recommended due to its small size and speed — even a short fall could be fatal.
Instead, enjoy observing its natural activity, such as webbing, hunting, and rearranging its substrate.
🧬 Lifespan & Size
- Adult Size: Around 2–2.5 inches (5–6 cm) leg span
- Lifespan: Females live 8–10 years, males 3–4 years
Though tiny, its bright coloration and engaging personality make it a standout display species in any tarantula collection.
🌿 Breeding Notes
Breeding Cyriocosmus elegans is considered intermediate in difficulty. Males are typically accepted if introduced carefully. Females produce small sacs of 30–80 spiderlings, which develop quickly under warm, humid conditions.
Due to their size, slings can be challenging to raise, requiring small prey and precise humidity control.
