This spider should not be handled. They are very skittish. While their venom is not very toxic to humans, some people are quite allergic to it.
Greenbottle Blue Tarantulas should be kept at temperatures of 80 to 90 degrees Fahrenheit with 40 to 60% humidity. The substrate, a mixture of peat and vermiculite, should be moist, but never too damp. Spiderlings need higher humidity, but high humidity can be fatal to adults.
Adults should be kept in 5-gallon tanks with several inches of peat moss/vermiculite mix and some shelters for hiding. The spiderlings should be kept in pill bottles with the same peat moss mix for the first couple months, then in deli cups until they are mature. Make sure that the adult tarantulas cannot climb up the side of their tank, as a fall can be fatal.
The tarantulas should be fed prey smaller than the length of its body. Spiderlings can be fed min-meal worms, while adults can be fed large crickets, anole lizards, super worms and pinkie & fuzzy mice. They should be fed a couple of large prey once a week. Adults can survive without food for as much as three months.
