Antilles Pinktoe Tarantula
Caribena versicolor
One of the most beautiful tarantulas on the planet. This Caribbean arboreal spider changes color as it grows: hatchlings are metallic sapphire blue, while adults explode in bright ruby reds, greens, and pinks. Very docile but lightning-fast and capable of jumping, it requires arboreal terrariums with exceptional cross-ventilation to prevent lethal lung fungal infections.

Species description
Geographical Origin and Habitat: Exclusively endemic to the volcanic island of Martinique in the Caribbean. It is a strictly arboreal spider that weaves complex silk tube webs among giant bromeliads, in the hollows of tall trees, and even under the roofs of rural houses.
Taxonomy and Genetics: Theraphosidae family (tarantulas). Previously classified as Avicularia versicolor. It has no man-made morphs; its natural genetics are already a rainbow. The stunning feature is the chromatic mutation (ontogeny): babies (slings) are bright electric cobalt blue; as they grow, the carapace turns emerald green and the abdomen bright ruby red covered in thick magenta fuzz.
Behavior and Habits: Titanic webbers. They never dig in the dirt. They spend their entire lives inside or near their high-placed silk funnel. They are New World tarantulas: very docile, rarely bite (very weak venom), but are incredibly fast. They can make impressive jumps to catch flies or escape danger (they shoot liquid feces if frightened).
Morphology: They reach a legspan of 5-6 inches (12-15 cm). They possess large light-pink hairy pads on the tips of their legs ('pink-toe') acting as micro-suction cups to scale any surface, even perfect glass. Sex is difficult to determine visually until maturity, when adult males become very slender, with disproportionately long legs, and die shortly after developing reproductive bulbs (palpal emboli) on their pedipalps.
Care, breeding and tankmates
Terrarium Setup: Demand vertically oriented enclosures (e.g. 8x8x12 inches tall for an adult). The FUNDAMENTAL parameter (cause of death for 90% of beginners' specimens) is CROSS-VENTILATION. The terrarium must have holes not just on the roof, but along the side walls to let air flow through. Decor requires a large diagonal piece of cork bark, around which the spider will weave its web tube.
Lighting and Heating: They shine at normal household temperatures (75-79°F / 24-26°C), tolerating drops down to 68°F (20°C) at night. Above 82-86°F (28-30°C) they will suffer severe heat stress and lethargy. They need absolutely no lighting and hate direct light: the scorching sun will turn their web tube into a death trap greenhouse. Heat mats are strictly forbidden, or at least NEVER placed on the bottom.
Humidity and Hydration: They require high humidity (70-80%), but stagnant air kills them instantly (often called 'Stuffy Environment Syndrome' or SADS). It is better to keep the terrarium drier but well-ventilated, rather than soggy and asphyxiating. They must always have a small water dish glued to a high branch or the glass, as they rarely descend to the floor to drink.
Feeding and Supplementation: Formidable arboreal insectivores. Spiderlings (blue slings) should be fed twice a week with flightless fruit flies or pinhead crickets. Adults eat every 10-15 days, preying on crickets and large locusts. They often bolt out of the web tube, pounce on the prey, and carry it back inside to consume in peace. In pre-molt, they seal the silk tube shut: they must not be disturbed or fed during this phase.
Compatibility: Absolutely cannibalistic and solitary like almost all spiders. Putting two specimens in the same enclosure equals providing an expensive meal to the stronger, faster spider. NEVER mix species.
Health and Common Diseases: SADS (Sudden Avicularia Death Syndrome) is the name given to the sudden die-off that strikes this species in inexperienced hands: it is not a true genetic disease, but the consequence of keeping the animal in an enclosure that is too humid, hot, and devoid of fresh flowing air. Their book lungs collapse if the air is stale. They do not have abdominal urticating hairs to kick; instead, they rub them directly against the target (contact urtication).
