Introduce all you want...as long as they're in a bin or something behind a solid sheet of glass.
Do your Palmettos measure up to the
Goliath bird eating tarantulas ? Them things get to the size of a dinner plate, don'tchaknow. I got to meet one face to face (through a nice thick sheet of glass of course!) and let me tell you, I wouldn't want to find that great bloody beast in the ceiling corner of MY bedroom, else there'd be a me-shaped hole in the opposite wall, drywall, framing and bricks be damned.
