Finally, the essential aspects of keeping crabs have been met. It is now time for the fun stuff, decorating the cage. One thing to consider when picking out decorations for hermit crabs is they like to climb; they are called tree land hermit crabs for a reason. Do not put decorations too close to the top of the crabitat unless it is secure because crabs are great escape artists.
A good rule to follow is “if it can go in a fish tank, it can go in a hermit crab home.” Be sure to provide plenty of hiding spots for the crabs; these are available commercially or can be crafted from home. Have fun while setting up the crabitat, the more there is for the crabs to do, the more enjoyment they will be able to provide. It can be fun to add a second level to your crabitat, leave it a few inches from the top so the crabs do not go for an adventure by themselves. Another idea for the cage is to supply the crabs with climbing equipment. A good start is a plastic basket, like strawberries come in, turned upside down. This will give the crabs something to figure out as they maneuver over and under it.
Hermit crabs like to escape and enjoy an occasional romp outside of their enclosure. Perhaps they could stroll across the kitchen floor or table, protected of course. It is a good idea to mist your crabs with water if they are going to be out of the humidity for any length of time, this will help prevent the modified gills from becoming too dry.
Welcome to the world of hermit crabs, they are facinating little creatures. Perhaps the hardest part to owning them is not buying a new addition at every pet store, as they have a tendency to become addictive. Take care of them, they will provide you with years of enjoyment in return.
