Goliath Birdeating Spiders
Goliath Birdeating Spiders do not like or need artificial light. For arboreal species you need a taller tank and fill it 1/3 of the way up with substrate (at least 4 inches) then you add in the fake plants and hiding places and place the water bowl in a dugout where it will not be easily spilled. Make sure that the lid of your aquarium is on tight because tarantulas are strong enough to move them if they are not locked down!
Tarantulas do not need any heat sources either. They do well at room temperature.
For terrestrial species you can get longer/wider tanks and fill them about ½ way full of substrate. They like to burrow. Then you place hiding places about in a way that you like and bury the water dish. Again, make sure that you lock the lid down!
Tarantulas do not eat a lot, but make sure there is a cricket or two available in their cage for consumption. Other insects can be used, but crickets are readily available and easy for tarantulas to digest.
