I'm guessing you are talking about a non venomous snake? Tarantulas are venomous. Some more potent than others but they all are. Look up bite reports. They can go from, feels like a bee sting to... Throwing up for a few days, tunnel vision, muscle cramps, high fevers etc.
Will all respect, you might want to start off keeping a few Wolf spiders or Jumping spiders.
