HCA: Hermit Crab Association

I have a twenty gallon long, the substrate 7'' deep, my in-tank temp is 75 degrees. All of my hermits have a complete diet of shrimp, veggies, fruits, nuts and other hermit-safe foods. With all this being said.. It seems like an act of aggression to me.. D:

I adopted a female jumbo about a year ago, since then she has killed and eaten all of my crabs. I'm not sure if this an act of aggression, or if this crab as psychological issues? Please help. This crab has been a nightmare

Ok! thanks so much! I'm sure it'll be fine. I was just worried about it, like all hermit crab parents do about their shell babies

My sister went on a trip to get 3 jumbo hermits for me, about 12 hours away.. she's going to be driving back home, how can she keep them alive and healthy the whole trip?

Ok, thank you! Cloudy (the female eq) just accepted some organic applesauce mixed with raw honey

Alright, I'll try your suggestions, thank you so much!

She's about one inch in length,( she's the smallest hermit I've ever owned!) But, anyways yes, she digs burrows all the time.. but don't hermit crabs tend to eat a lot before they molt?

Hanging out on my shoulder My Equadorian, Julian loves hanging out on my shoulder! He's always been my buddy since I adopted him

She's currently in a 20 gallon (long) tank, along with 3 other hermits.. I give them fruits, veggies, eggs, nuts, and oats everyday.. The substrate is coconut fiber mixed with sand, its about 6 inches deep. The temp of the tank is 81 degrees.. the humidity level is about 80. I have a fresh water and...

I adopted 1-year old female equadorian about a month ago, she was eating normally for awhile, then she just stopped! I haven't changed anything in their diet, but I still can't figure out what would cause her to stop. Recently she started staying in her shell and being very sluggish.. what do I do???
