One of CSJ's most important goals is that our information be kept current AND valid. This means a lot of work to change the popular mind set in other hermit crab communities. Our mission of education is always ongoing.
Our history is long…
CSJ has just migrated to it's fourth new home...starting on Yahoo Groups back in 1999, then to NukeEVO, then XOOPS and now here on BuddyPress. All relevant articles and content have moved with us over the years. So while the items posted have my photo and name, I am not the author of all this valuable information. The original author has been credited where ever possible. We thank all those dedicated crabbers who went before us and contributed to our vast library of information.
OCEAN CITY, N.J. — You wouldn’t know it by the petite tank in tow, but the Merchlinsky family emerged from George’s Beach Shop on the boardwalk in this Shore town on a recent sunny day with three new pets…
GAINESVILLE, Fla. —- A 5-million-year-old saber-toothed cat, the worldâs oldest grape and a bizarre hermit crab were among more than 100 new species discovered by University of Florida scientists last year.
Gustav Paulay dredged from the deep sea a new hermit crab that exemplifies a rarely documented process in which hermit crabs move out of their shells and harden their bodies to resemble true crabs.
Our beloved hermit crabs are ectothermic creatures, which means they depend on the environment to regulate their body temperature. This means maintaining their crabitat at proper temperature and humidity is literally a matter of life and death.
With warm summer temps comes the risk of a too hot crabitat, below are some tips to help cool down your crabbies on a blazing hot day.
First remember that hermit crabs are tropical creatures so they can handle brief temperature spikes and be okay. A prolonged heat wave will be too much for them to handle. If you cool your home by opening windows and using fans, you must keep a close watch on the temperature in the crabitat. If you have air conditioning and maintain a fairly consistent inside temperature, the tank temperature shouldn’t vary too much.
82F is the upper limit for crabitat temperature. Your tank should have a range of temperatures. Ideally with the coolest part of the tank being 72F and the warmest part around 80F. Be sure to check the substrate temperature and the air temperature. In the summer, a cooler substrate temperature is ok. That will allow your hermit crabs to burrow to cool off. The opposite is true in the winter.
These are temporary fixes for a spike in temperature and not ideal for maintaining a proper crabitat environment day to day.
Consider moving the crabitat to a cooler part of the house if an extended heat wave is expected. Pre chill some dechlorinated water so you have it on hand.
Try removing the lid and use a fan to quickly cycle hot air out. The fan will cause a drop in humidity but that will be okay. Overheating is a bigger danger. If you have your crabitat set up properly, the change in humidity will be brief and will not harm healthy hermit crabs. Consider a cold water misting after using the fan, use dechlorinated water.
Freeze some plastic bottles of water and pop one in the crabitat to cool it off. Replace as needed on a hot day. Freeze these now so you have them when you need them. Those blue lunch box freezer things can be used too, but not if they are leaking or are of a soft material the hermit crabs can puncture. If you use these I would not leave them unattended for too long.
Make sure their water pools are not hot. Cooler water can help them cool themselves.
If you have to use ice cubes to cool off the crabitat, place them in substrate and not in the water pools. Unless of course you were clever and froze some dechlorinated water. :)
Hermit crabs will hang out of their shell in an effort to cool themselves off. If you see this behavior, act fast before permanent damage occurs.
Leaking of brown liquid or bubbling/foaming at the mouth are signs of severe overheating and what is likely irreversible physical injury to your hermit crab.
Warmer temps are here! Don’t forget to check your crabitat to make sure the temps aren’t creeping outside the acceptable ranges. If you keep your air conditioner on you may not see a big change in the crabitat. However, if you rely on open windows and fans to cool your house, you really need to keep an eye on the crabitat temperature.
