An average person needs 950000kl per day
hermit crabs, definitly. turtles need hige tanks and lots of cleaning. hermit crabs also need much more care than you think they do, but not as much as a turtle.
Most crabs eat once or twice a week, depending on the size. A much larger crab would need to eat much more often, however.

hermit crabs need to live in 70-80 degree temprature
Crabs need shells because there abdomen is very soft and sensitive and the shell protects them.
No. Hermit crabs live on huge beach colonies and are accustomed to working and traveling in huge groups. Crabs really need to be kept in groups (best case scenario would be in same species group). Crabs should be kept in groups of 3 or more.
