I mentioned in the "Passions" thread that one of my passions is rescuing Land Hermit Crabs; those little crabs in painted shells that you can buy at mall kiosks and beach shops everywhere. They actually require very specific care that usually isn't met by the average person who buys one as a souvenir from the beach. Most pet shops sell inadequate and down right dangerous (to the crabs) supplies for them. In a nutshell, they need an aquarium with a glass lid; deep substrate (3 times the depth of the largest crab); decholrinated fresh and salt water bowls deep enough for them to completely submergea source of heat and a source of humidity. Ideal heat and humidity is 82 and 82% relative humidity. They need organic foods from many, many sources such as meats, nuts, grains, leaves, bark, fruits, sea weeds, vegetables, feces, molds, etc. They are scavengers in the wild and are genetically programmed to not eat the same thing twice in a row. They can eat almost anything as long as it is organic or wild sourced, not processed, and unseasoned. The little creatures, if properly cared for can live for upwards of 30 years in captivity and 70+ years if left in the wild, where they belong. The painted shells often cheap land snail shells painted with toxic lead based paints. I currently have 13 in two different tanks. My two oldest are 9 years old and in shells the size of baseballs. I have 6 med-to-jumbo sized crabs in a 55 gallon tank and 7 micro-to-small sized crabs in a 40 gallon tank. I personally don't believe they make good pets and they definitely should be banned. They are literally tortured from the moment they are captured to the moment they wind up in someone's tank. Under the best of care they will survive. Most don't.
