Mastering the Care of the Vibrant Euathlus Species
The Wow Factor
If you are looking for a tarantula that packs an incredible amount of beauty into a small package, look no further than the Chilean Emeralds. This group includes the vibrant Euathlus manicata and the highly sought after Euathlus sp. "Smaragd Tiger" (Emerald Tiger). Hailing from the diverse landscapes of Chile, these species are the "gemstones" of the hobby. They are famous for their iridescent metallic green or gold carapaces and the striking colouration on their abdomens. For the tarantula keeper, a Euathlus offers a rare combination: the exquisite detail of a high-end exotic and the legendary "puppy-dog" temperament of a Chilean dwarf.
Size, Growth, and Longevity
These are "dwarf" to medium sized terrestrial species, with adults typically reaching a diagonal leg span of 8cm to 12cm. Because they are built for life in cooler, arid regions, they have a very slow growth rate. It can take several years for a spiderling to reach its full, shimmering adult colours. However, this slow pace is linked to an impressive lifespan; females are incredibly hardy and can live for 15 to 20 years. In the tarantula hobby, they are prized as "forever spiders" low maintenance companions that stay small enough for compact enclosures but live long enough to be a staple of your life.
Temperament and Suitability
The Euathlus genus is world renowned for having some of the most docile temperaments in the entire arachnid world. They are famously inquisitive and slow-moving, often showing more curiosity than fear when their enclosure is opened. While they are a new world species with urticating hairs, they are notoriously reluctant to use them, and a threat posture from a Euathlus manicata is almost unheard of.
Because of their calm nature and manageable size, they are perfect for beginners and advanced keepers alike. In the hobby, they are often the "gateway" spider for those who are nervous about larger, faster species. Their gentle "plodding" walk and stunning metallic colours make them a joy to observe during maintenance.
Simplified Care
As inhabitants of the Chilean scrublands, these spiders are remarkably easy to house in the UK. They do not require large, sprawling setups; a medium-sized terrestrial enclosure with more floor space than height is perfect. They are opportunistic burrowers, so provide 8cm to 10cm of dry substrate.
Environmental needs are simple: they thrive at room temperatures between 20°C and 24°C, making them one of the few species that genuinely enjoys the typical UK home climate without extra heating. Humidity should be kept low to moderate (40% to 50%). A shallow water dish and a small cork bark hide are all they need to feel secure. They are steady eaters, though because of their slow metabolism, they do not require feeding as frequently as larger, faster growing giants.
Conclusion
The Euathlus manicata and Euathlus sp. Smaragd Tiger are true masterpieces of the Chilean wilderness. Their metallic emerald carapaces and gentle, inquisitive personalities make them a unique highlight in any collection. For the UK keeper who appreciates slow-paced, beautiful, and exceptionally docile tarantulas, these emerald spiders are an unbeatable choice. They prove that the most beautiful things often come in small, shimmering packages.
