Grammostola pulchra spiderling • 3/4″ (Brazilian black tarantula)

Description

Listed for sale are captive-bred Grammostola pulchra spiderlings (pulchra = beautiful). There are other black tarantulas in the hobby, but somehow G. pulchra has long stood at the top of the heap. Size, build and gentle disposition surely contribute. Drought tolerance, low maintenance and longevity should be added to the list. The Brazilian black lives among the dry plains and rocky outcrops of southern Brazil.

We raise G. pulchra spiderlings like these on slightly dampened substrate: 1 part water + 10 parts dry substrate. We limit ventilation enough to allow some humidity to build. For juveniles and older we use less dampness, less humidity. Room temperature (68-72F) is fine although growth is faster at 80-85F. A water dish can be useful if only to ensure against dehydration, especially if ventilation is liberal.

Growth is on the slow side, but with proper care, female G. pulchra easily reach 5+ inches and live on the order of 20-25 years. It’ll take 2-3 years before your spiderling reaches a size that is sexable by molt. Females typically take 5-6 years to mature sexually. Subsequently they’ll increase in size a small amount with each yearly molt.

Care highlights:

• slightly dampened substrate for spiderlings

• room temperature (68-72F) up to 80-85F
• calm, may flick hairs if disturbed
• consider a hide, forest litter and plantings for enrichment
