If you haven't found the size or style of the hermit crab shells you are looking for don't hesitate to ask. Fights are very common in the following scenario, and there is nothing you can do about them besides separating the crabs and buying more shells:.
If you notice the crabs making noises back and forth or trying to steal shells, buy a few more shells for them to choose from. I had a crab who held a grudge over this scenario for more than a month: Crab B didn't stay above ground for more than an hour at a time until Crab A switched into a new shell and was no longer harassing B for stealing her shell! With the exception of the first photo from flickr, the hermit crab and shell photos used on this page were taken by the author, fritteritter; other photos were taken by photographers at sxc.
CJ: If you are usually in temperature, or your temperature at home is not too different from where you the crabs, you don't need a heat lamp or heat pad. If you live inland your humidity may be lower than needed. In this case you can put natural sponge with water in cage or a wet towel over a portion of the lid to add more humidity. You also don't need light source if you have the crabs where sunlight comes in but don't put cage right in front of window, so you don;t overheat them.
To disinfect it you can put it on the stove until it is boiling and let it cool. If you eat fruits, vegetables, nuts, you can give a little to the crabs along with tiny pieces of leaves.
BTW I also just noticed that a caribbean hermit crab does not require salt water. The crabs I have are identifyable as caribeans but I do not know if this information is true. I live in puerto rico and found my two hermits out of the wild, one is slightly smaller than a golf ball and the other is about three inches in diameter.
They have a nice encloser with plenty of rocks to climb on but not much sand. I am planning on getting more sand from the beach but have a few questions.
First, should I give them a heat lamp? I found one in a thicket of trees by the beach and the light there was not too bright so I am guessing that the light from the sun shining into the carport is enough. The two crabs are very social and have climbed all over the structures in their aquarium.
I gave them fresh water in a small ceramic dish that they have been drinking and washing around in, we got them yesterday and I have already replaced it twice. However, we do not have immediate access to fresh salt water as we live a few miles inland and are about minutes from the nearest beach.
What should we do about the salt water? I have also given them mango leaves which they have only walked around on and fed them some scraps of banana that the large one has taken a few bites of. They are very happy however, crawling around in their little habitat. How can I determine which type of hermit crabs I have? Can I make salt water using sea salt? Last question is Please do Not buy shells that have been painted. These shells will poison, and kill your hermit crabs. The paint is very bad for them!
There is always some chance that the painted shell could have negatively affected the crabs while they were at the pet store, but they are probably fine.
The painted shells should not be a long-term home for your crabs, just be sure to provide a selection of natural unpainted shells that are the right size as well as a bit larger. They will switch shells when the time is right; don't try to force them to switch. You will need to remove the painted shells once they are vacant, but you should wait a few days after a shell is empty before removing it to make sure that the crab is satisfied with their new natural home.
We have hermit crabs also. I have written about them as well. You article is very informative. I am wondering if the shells my crabs have from the pet store are not safe? I am hoping they seem to be fine and plenty active.
Much more frequently when they are small than larger crabs. Each "shell shopping" expedition might involve a few shell changes until they find one that they like. Small crabs may go through 3 or 4 shells in a year, provided that their habitat allows them to dig underground to molt and grow larger.
If they are changing more frequently it may be time to buy more shells to find one that the crab is happy with. Large crabs may keep the same shell for years, but they should always have a few appropriately-sized shells to choose from.
Also, some species such as Ecuadorians hold onto the same shell for longer than the more common in the US at least Purple Pincher crabs. They will stay underground until they're done molting. Occasionally they may dig underground for some reason other than to molt, but in any case, once they are underground you should not and do not need to disturb them. If you notice that the crab buried underground, the best food to provide is dry food that will not go bad, especially something with calcium and nutrients like cuttle bone or oyster shells.
There is no need to provide fresh food every day when the crab is underground, but you should keep dry food so that it can eat if it resurfaces. It may be underground a few days or a few weeks. After molting the crab will crave the calcium and other minerals found in foods like cuttle bone in order to replenish its supply of nutrients that may have been exhausted while molting. The water should be changed weekly or more often to prevent stagnation or algae.
Just ensure that the sand stays "sand castle consistency" rather than becoming too dry so that it is moist enough for the crab to dig back out. Just pour a bit of dechlorinated water on the sand when you refill the water dish if the sand is getting dry. I have a question: Once the crab is under substrate to molt, does he just stay there for a month or two or does he come up now and again. If that is so, do I need to add water to drink and food to eat every day? This is all new to me and I have no idea about all of this stuff.
Thanks for your help and do I ever need it! The answer depends on how much space they have and whether all the standard needs are met.
If conditions are not good or there is not enough space they may be more prone to aggression or general clumsiness, but otherwise size does not cause a huge problem.
