Hermit crabs fighting in temporary tank…not eating either
My new hermit crabs I rescued from a travel container from a person on Craigslist yesterday. They were in the travel container for a month before I got them. They did not have proper access to food or water. Anyways day 2 at my house and they aren’t eating, just literally skipping over snout and shell fruity buffet, dried mealworms, dried shrimp, and fresh banana and cucumber. I look over after hearing chirping coming from the tank and see two crabs brawling at night. I had to separate them from fighting. I’m not sure if I should go ahead and setup the 40 gallon tank for the even though post purchase death syndrome is a real risk. I really don’t know what to do. Please help! First time hermit crab owner here.
I ordered them some new shells as well, 6 shells that should fit them all, not sure what I should do at this point. Shells don’t come for like a week though. Seems like they are all liking to fight with each other just had to break up another fight for the second time.
