Grammostola mendozae
Common name: Unknown
Indigenous: Argentina
Habitat: Temperate climatic conditions prevail throughout most of Argentina, except for a small tropical area in the northeast and the subtropical Chaco in the north. In Buenos Aires the average temperature range is 20° to 30°C (67° to 86°F) in January and 8° to 15°C (46° to 60°F) in July. In Mendoza, in the foothills of the Andes to the west, the average temperature range is 16° to 32°C (60° to 90°F) in January and 2° to 15°C (35° to 59°F) in July.
Temp/humidity: 65°-78°(18.3°-25.5°C) /55%-65% humidity. I keep this species temperature at 78° (25.5°C)  and the humidity at 65%.
Enclosure: This is an opportunistic burrower. As a spiderling, I used a vial that would allow at least three inches (7.62cm) of substrate for burrowing. As sub-adult-adult I use a terrarium that will allow at least four inches of substrate
Substrate: I use four inches (10.16cm) of substrate. (I use a mixture of peat moss, vermiculite, coconut fiber and dirt for firmness, as the substrate).
Retreat/Hide: I Place a bark for a starter burrow hide.
Food Consumption: I fed the new born spiderlings fruit flies, than when they reached 1/2" I introduced baby crickets. My adult Grammostola mendozae, I give two (2) one-inch B. dubia roaches or five (5) adult crickets weekly. This species is a so-so eater. It doesn't attack its prey with a vengeance, but she always eat her meal within a days. The only time this tarantula refuses food is when it is near a molt.
Water Requirements: I keep a water dish in the tank. I have never seen mine drink. I keep the substrate in the terrarium dry.
Growth Rate: The growth rate of this species is medium. I purchased this tarantula as a spiderling.
Adult Size: I read that they get six inches (15.24cm). After seven years my G. mendozae has grown to seven inches (17.78cm).
Temperament: This is a laid back, easy to handle species. It has never kicked hair at me nor given a threat pose. She is always out in the open and is friendly.
Comments: To own one of these is to truly have a pet tarantula. When I open her enclosure, she always climb up the side of her cage. If I put forth my hand she will climb on it. It seem as though she welcome the contact. Every tarantula owner should have one of these. This is definitely a beginner species, it is also easy to care for and hardy.
