Cupiennius salei
Cupiennius • Trechaleidae
Cupiennius salei is a big, fast, largely arboreal wandering spider from southern Mexico and Central America. It does not build a capture web; it sits on leaves at night and ambushes prey. Keepers describe it as tolerant and a good first true spider. One experienced keeper uses about 25 C (77 F) with 70 to 80 percent humidity, a tall enclosure with cork bark and plants to climb, and slightly moist substrate. Many keepers skip the water dish and drip water onto the cork instead, which the spiders drink. Feed fruit flies to hatchlings, then crickets; one keeper feeds adults every other day, another twice a week. Never leave live crickets in with a spider that may molt. The bite is not considered medically significant, but expect a quick runner when it is disturbed, so open the enclosure carefully.
