So, we get home and, not wanting to be an ignorant "poacher", I start researching the little guys on the net. Whoa, whoa, whoa! Hermit crabs require a specific humidity level range (75-85%) in order to survive, otherwise they will slowly suffocate to death! Hermit crabs require a specific temperature range (73-85 degrees), otherwise they will die. Hermit crabs molt (a stressful process) and require a proper substrate (play sand and coconut fiber are good, gravel is bad!) in order to bury themselves so they can shed their exoskeleton. Hermit crabs require lots of extra shells, as they are constantly searching for just the right home (if the crabs can’t find the right home they get stressed). If hermit crabs don’t have the right shell, they will fight other crabs for their shells (known as "shell fighting"). Hermit crabs shouldn’t eat the commercial crab food, they should eat "regular" food (they are scavengers after all), but only certain kinds of food (for example, iodine is bad for them and could kill them). Painted shells are bad. The paint chips off, they eat it, and can die.
The guy at the store (and his little pamphlet) didn’t tell the whole story. No sir, far from it in fact!
Armed with this knowledge about hermit crabs, I set out to create a good environment for them to thrive so my kids can enjoy them. I get a spare 20 gal. tank from a family member. I get play sand, temp/humidity gauges, plenty of extra shells of varying sizes, hiding places, an under-tank heating pad, fake plants, two water bowls (one fresh, one salt), the whole nine yards - over a $100 bucks, easy. The temperature seems right. With periodic water spraying, the humidity seems right. Thanks to a "hermie menu" I found online, the food seems right. I even bought a few more crabs (as they are social creatures, the more the merrier). The crabs seemed happy and content…
Wrong! One guy molted and never came back up. Dead! One guy was ripped out of his shell by another crab and had his back four legs ripped off! Found him "naked" by the water pool. Dead! Another guy was ripped out of his shell and had two legs missing. Dead! Another guy just plain expired, probably from stress from all the death and destruction around him. There should be two "hermies" left, but I find only one. The missing one was apparently eaten alive during the molting process (as can, apparently, happen)! Eaten alive!? Jesus, it's like Agincourt or the Somme in there! The tank has a horrible smell of death! My kids don’t even want to look at the tank anymore. It's too depressing!
I did everything I was supposed to do (and more) and our little colony didn’t make it to six months! Well, there is actually one guy left. He's our little "shell-shocked" hero. But he'll probably die some horrible death soon, too.
Anyway, that's our story. Be forewarned, these guys are not so easy to care for, no matter what they tell you at the store!
