Chaco Mousy Brown TarantulaÂ 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 Â½ 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.
The Chaco golden knee is a large tarantula, being able to reach between 7 and 8 inches in legspan (17.8-20.3 cm). Being a terrestrial tarantula, it has a heavy body. Mature males have longer legs and smaller bodies than females, and they possess tibial hooks or apophyses to hold back a female’s fangs during mating. Males also possess modified pedipalps to insert sperm into the female’s genital operculum. It exhibits a multitude of colors, with bright yellowish leg stripes, dark black “femurs”, and pink hairs all over its body. As with the rest of the genus Grammostola, the Chaco golden knee has very large fangs, and the carapace (the top of the prosoma) is raised to make room for the large chelicerae. It has rudimentary eyesight, and senses its environment with the setae all over its body, feeling vibrations through the ground and air, and picking up chemical signatures, similar to a sense of smell.
