I love tarantulas. Always wanted one as a kid. Back in 7th grade, we got two for our science class, and used one aquarium w/ 1" thick styrofoam splitting it into two sections. Came back the next day, to find one spider on the foam wall, next to a big hole, and the other spider dead, upside down in its own section. I guess the wall-climber killed and ate the other one.
