Some hermit crabs do fight. I week ago bought two hermit crabs. At first I bought one and then I read that they like to be with other crabs so the same day I bought another. The first one i bought was really active before I got the second but slowly I saw him retreat into his shell. Yesterday I found him without a leg but I never saw the crabs fight so I didn't think that was the reason. However, today I cam home from work and found the first one ripped apart in the cage. After some research I learned that they fight over shells and actually do rip each other apart on occasion. I have had about 15 hermit crabs throughout my 25 years and I never knew this fact. So, if you find your crab is acting weird with another crab move them to separate cages.
if they are two males it courtship they will fight near or to the death for a female
Why are female crabs called jenny
You can eat female crabs. However, most people will throw female crabs back so they can preserve the crab population.
can fitler crabs live together
no
Males are Jimmies and females are Sally or she crab for immature crabs and Sook for a mature female.
Hermit crabs are very social and LOVE company they usally don't live as long as they do when their with others. They can live over 2 years mine lived for 3 years. Hermit DO FIGHT they fight over shells. one likes a shell the other has (make sure your hermies has alot of shells, NOT over crowding the tank!) and they fight. The victim usally dies over the fight. But if you are there when it happens, you should blow on them if they still fight pick them up (do NOT pull them one will lose a limb!) if that doesn't happen you need to LIGHTLY mist them with distilled water.
There is no difference in size between female and male hermit crabs.
by rubbing their big claw on there body
yes they are whatever you want them to be.
Crabs do get afraid, especially of predators that will harm and eat them. Crabs that feel in danger will use their pincers to fight back.
Female crabs typically mate once or twice in their lifetime. The timing of mating varies depending on the species and environmental conditions. After mating, female crabs can store sperm for later fertilization of their eggs over several reproductive cycles.
