Not all Hermit Crabs are the same in terms of changing their shells
Some change their shells frequently, while some of them are rather reluctant and just stick to the shells they are currently sheltered in. Hermit Crabs native in the Caribbean changes their shells frequently compared to Ecuadorian ones who tend to stick to one shell for their shelter for a really long time even though they are too big for the shell.
Molting also plays a part in their shell changing but this may happen before or after molting.
Variety is Good, especially with their shells
Just like us humans, hermit crabs are picky as well with their shelter especially if you provide them with variety/options for their shells. So as a hermit crab owner, it’s your job to provide them a variety of shells with different shapes and sizes.
Failing to do so will make hermit crabs fight over the best shells in your reef. Yes, hermit crabs do that, they will fight other hermit crabs for their shells. Make sure the shells you will provide aren’t damaged because just like mentioned above, the shells are vital to their gills for breathing.
Important Things to Remember in Choosing the Shells:
Don’t worry, there are lots of options to choose from and available to buy in pet stores. Though as a disclaimer, you may find yourself on trial and error to find the right shell for your hermit crabs.
- Size: Provide a variety of sizes, with similar openings. If you have small hermit crabs then provide them with their size and with slightly bigger ones because they will eventually move on those shells once they grow.
- Openings of the Shell: Check the openings if it’s: round, oval, and D-Shaped. Preferences of those openings will vary depending on the species of your hermit crabs.
- Quality: When it comes to providing shells, always remember that it’s still quality over quantity. Check if the shells you’re going to provide aren’t damaged or if the shell’s openings suit your hermit crabs.
Also remember to sterilize the shells as well, boiling the shells for five minutes will help. Drain and let it cool before giving it to your hermit crabs. This will remove any bacteria present in the shells that may harm your hermit crabs.
Are Painted Shells also an Option?
Yes, it is also an option. It is also offered mostly in pet stores but if there are natural options go for it. And if you’re going to resort to painted shells, make sure that the paint used is toxic-free and won’t harm your hermit crabs.
It’s also important to note that painted shells will deteriorate over time and those paint will fall off and your hermit crab might pick it up and eat it, if there are better options out there go for it.
