There are six types of hermit crabs available for sale in the United States. All of them are in the genus Coenobita.  The most common type out there is the Caribbean (Coenobita clypeatus,) which is also called "PP" for purple pincher due to, you guessed it, its large purple pincher. Wild Purple Pinchers are found in the Caribbean Islands. Most likely, when you see a hermit crab in a store, you will be seeing one of these guys. The Purple Pincher is the best one to start with because the others are more delicate and require much more detailed and intense care. The other types are Rugosus "Rug" or "Ruggy" (rugosus), Strawberry (perlatus), Ecuadorian or "E" (compressus), Cavipe or "Cav" (cavipes), Komurasaki "Viola" (violascens), Indonesian or "Indo" (brevimanus). Be patient with them when you first get your hermies--they will take a little time to adjust to their new home. When you get your hermit crabs, leave them in the cage for a few days. When you see that they don't hunch into their shell when you pass by then wait another day and try to hold your hermit crab. Let your hermit crab explore your hand and get used to you. Once you get them home, they go through a "De-stressing" period that can take as little as a few days and as long as two months. During this time, change out their food and water regularly and do not disturb them. Sometimes, even with the best efforts of even the most experienced crabber, hermit crabs can succumb to Post Purchase Stress (P.P.S.), and die. If your crab digs under the substrate for a couple of weeks, don't worry. As long as it doesn't stink like dead fish, he's OK. Please do not disturb your crab during this time. He will need to be alone and if he is bothered, the stress could kill him. Once in a while, a crab's exoskeleton gets a little tight, and like a snake shedding its skin, a crab will shed its exoskeleton and grow a little bit. Don't take the exoskeleton away from the crab! He will need to eat it in order to harden his new exoskeleton. If you have a sick crab, don't...
