if someone asks me to name an "easy" pet to take care of, tortoise doesn't leave my lips until way down the list.
>>"In terms of difficulty I usually list herps this way... Snakes, lizards, tortoises, turtles and then amphibs in the order of easy to difficult."
before the UVb technology and information boom, i would have placed most lizard species more toward the end of that list, but even with all the available information, tortoises are a worthy challenge.
under the right conditions and with ample information seeking behavior on your part, you can successfully maintain a tortoise. just don't make the mistake of equating "easy" with "occasionally tossing a piece of lettuce their way."
take brad's advice and visit a site like russiantortoise.org to get an idea of the effort most of us consider reasonable for success.
good luck -- if you're into it, tortoise keeping is amazingly rewarding.
