We came home from the beach yesterday with three land hermit crabs. I knew my 8 year old daughter would ask for some. I did some research online while we were there to make sure I knew the basics, so we chose 3 yesterday morning right before heading home (I'm pretty sure they are all "purple pinchers," a Caribbean species). We already had an unused 10 gallon aquarium, so after we got unpacked, the girls and I headed off to the pet store for the food and dishes and a hiding log. I got all-purpose sand at Home Depot and made sure it was moist, then put in a dish of fresh water, a dish of salt water, and a bit of food and their hidey-log. Once they discovered the salt water, they drank lots of it. The dish was almost empty this morning. We have a thermometer and a hygrometer in with them and they seem ok for now. The biggest retreated under the log, dug out a shallow hole, and hung out there most of the day, but is venturing out now. The other two crawled around a bit but not too much. We know they are nocturnal and that's fine. We did get to see them crawling around exploring last night and eating a bit. They are really cool to watch. Thank goodness for the internet and all its information. No wonder so many hermies die in captivity, the way they are fed and handled (meaning incorrect temp and humidity, and lack of proper substrate. Hermies do not do well living on aquarium rocks or plain wire cages). I hope these guys do well. It's kind of like with chickens- I am already saying "They need more space," and more this and that. . . if I'm going to have them, I want to take care of them as best I can!
