nope! most people own hermit crabs and have them in tanks with sand.
they stay in the same place
No, they're HERMIT crabs which means they could stay in a cave or some other outside-ish enviroment.
Hermit crabs love a large area with lots of space to play in and plenty to climb on an old aquariam tank is perfect for hermit crab/s
Hermit crabs find food, eat it until full, and stay near food until it's gone.
Yes they do. Out in the wild hermit crabs live in groups up to hundreds. but in captivity i would have at least 3.
In oxygenated water hermit crabs can survive for a short time. Straws can stay under the longest as their modified gills most closely resemble marine hermit crab gills. However, the time varies between the species. Generally a hermit crab will only be under for a minute or two. As long as your pool has an easy way for crabs to get out they are good at regulating when they have been under too long. A hermit crab will not drown if he has a way to climb out.
hermit crabs are not true crabs, but are more closely related to shrimps. I read it in a book!Hermit crabs are more closely related to squat lobstersand porcelain crabs than they are to true crabs.Adding on to that, yes, Hermit crabs are very similar to true crabs. They are closely related, but not as closely as the aforementioned creatures.
NO they don't because they they stay in shell
Invertebrates, because they need to molt to grow. Hermit crabs molt underground and can stay there for weeks to months to learn more about molting please follow the link below this answer. Thanks ;)
Hermit crabs don't have a regular size because they grow, they don't stay the same size.
im pretty sure that not all crabs eat hermit crab food. unless that u mean that do all hermit crabs eat hermit crab food? then the answer to that is yes. all hermit crabs eat hermit crab food.
because they have 2 legs inside their shell to hold on to the shell
