After reading through some of the posts here, I am frankly amazed that I still have live crabs! My son got one from a touristy sort of place, and we brought him home in a round cage... where he lived for 8 months because I didn't know any better! Thanks to you all I now have a tank, with climby accessories, a sponge in the water, and some friends for poor lonely Chet. I've still not quite got it hooked up as well as you all do - but it's WAY better than what I had before. Poor Chet! He's evidently been a real trooper, and I will be a better mama now that I can benefit from the wisdom everyone here has to offer.
