Cyriocosmus perezmiles
Common name: Bolivian Dwarf Beauty
Indigenous: Bolivia
Habitat: Although situated entirely within the tropics, Bolivia has, as a result of its varied elevation, a wide range of climate. In the higher regions the climate is cold and dry. In the lower-lying regions the climate is warmer. The mean annual temperatures range from 8°C (47°F) in the Altiplano to 26°C (79°F) in the eastern lowlands.
Temp/humidity: 78°-82 °, 65-75% humidity.  I keep this species temperature at 82 ° and the humidity at 70%. I keep one-half 1/2 of the substrate in the terrarium basically dry. I mist the other side once every two (2) weeks.
Enclosure: Use a spiderling vial that will allow at least three inches of substrate for burrowing and four inches as sub-adult-adult.
Substrate: three inches of substrate in vial and three inches in small terrarium. (I use a mixture of peat moss, vermiculite, coconut fiber and dirt for firmness, as the substrate).
Retreat/Hide: Place a bark for a starter burrow hide
Food Consumption: I first fed her fruit flies, than when she reached 1/2" (1.27cm) I introduced baby crickets. Now I give my Bolivian Dwarf Beauty two one-half inch (1.27cm) B. dubia roaches or one 1/2 inch (1.27cm) crickets weekly. This species is an excellent eater.
Water Requirements: I keep a water dish in the terrarium. I have never seen mine drink.
Growth Rate: The growth rate of this species is fast. I purchased this tarantula as a spiderling of 1/8" (0.3175cm) in size. After the first year she has grown to one inch. With constant feeding and with temperatures in the low to mid 80's, it will probably reach full size within two (2) years at this growth rate.
Adult Size: I read that they only get two inches (5.07cm).
Temperament: This is a docile species. Whenever I open the cage, she doesn't run for the burrow. She has never kicked hair at me nor given me a threat pose.
Comments: I love Dwarf tarantulas. I consider a tarantula a dwarf if it does not attain a size over two and one-half inches (6.35cm) leg length. A three inch tarantula in my opinion is not a dwarf; small, but not dwarf.
The Bolivian Dwarf Beauty is another feisty, easy to care for dwarf species. It looks like a miniature Costa Rican Tiger Rump with a orange heart on the abdomen. This is a very likeable tarantula. This T also enjoy webbing its terrarium.
