i bought a tarantula from the pet shop the other day and it says its a cross between Lasiodora Parahybana and Lasiodora Difficilis.....now my question is how to care for it......i have the temperature in the tank at 68-70 degrees F and i'm not sure how to keep the humidity inside or how will i know if i have the right humidity.....and what to do to "up" the temperature that i already have....i have a heat pad underneath the tank already.....is sponge in the tank really not good idea? i am a new hobbyist....
