As of late, these large spiders are acquiring a more common place in the pet trade. The number of available species is growing rapidly due both to importation and private captive breeding programs. Tarantulas are relatively easy to keep, provided a few basic guidelines are kept in mind. When purchasing a tarantula one of the primary things to consider is the type of environment in which the spider is going to be maintained. Because all spiders are quite cannibalistic, each should be housed in an individual container.
Aquariums work quite well as suitable containers.
They are easy to obtain and allow a certain amount of creativity when establishing a habitat for the spider. A cover should always be provided for each container. It should be noted that the standard aquarium cover, whether a full hood or versa-style hood, is unacceptable because they do not offer a secure fit. Arboreal tarantulas, in addition to many of the terrestrial forms, can easily climb glass and make use of any openings or hinged parts to affect an escape. A secure-fitting cover should be used at all times.
