Hi Sassy! Glad you could join us!
Sounds like you have some crabs with fun personalities. They are each so individual, aren't they? My sister had crabs when I was a kid, and my parents managed to kill them twice, so she gave it up. Yes, you read that correctly. It was my mom who committed the deeds that led to their perishment, not my teenage sister. Mom meant well, but after the second loss, my sister decided that hermit crabs were just too much for my parents and chose not to get any more. Now my sister has moved on to dogs, snakes, amphibians, and the occasional reptile, and I'm the one with the hermit crabs.

My biggest crab is also my most often visible, and doesn't seem scared of me at all. My middle sized crab just wants to hide all the time, and my smallest is getting more willing to interact with me now that he's finished his first molt in my care.
So I thought, since my sister had them twice when we were kids, and I knew like three hermit crab owners, that I had a good idea what they needed. I was so very wrong... Crabs can live 10-20+ years with the proper care, not just the 1-2 years the petstore markets them for. But they need the proper food and habitat conditions to do so. That's what I think is so great about this forum, is that it's been around a long time, and there are many experienced crabbers who are members who have crabs that are over 10 years old, and have tried to combine their experience with the latest scientific and evidence-based research to provide crab care guidelines that will give us the best chance of helping our crabbies thrive (not just survive, but thrive!). I've only been a member of HCA and had crabs myself for about three months, but I have learned so much!
Here is a link to the care sheets. It's a bit of reading, so please, if you have any questions, make a post here or in the relevant subforum, and folks will be more than happy to help you out. Congratulations on your new crabbie!
