Nice dude!
Some advice: Keep 'em cool (below 75 degrees F [this is a MUST]), Keep 'em fed (otherwise they'll start biting off each other's limbs [they will regenerate, but it is still a very stressful ordeal, and can leave them open to infection]), and made sure ALL tank decorations cannot be swallowed (sand, gravel, rocks, driftwood, EVERYTHING).
These guys are cool, fun, and fascinating, I hope ya like them.
Also, I don't mean to steal you're thread so tell me if you want me to delete this. Here are my little (8") guys, Midas and Spike.
