I have 2 hermit crabs, is that enough?

  I won 2 hermits at the fair a few days ago, im worried that because they fight sometimes they don't like eachother, should i buy 2 more? Or will they get over there problems once i get them into a new bigger tank? ( they fight over a sleeping spot)
Ive had hermit crabs before. They are most often okay if they are the same size. make sure there is a good quantity of shells available as that could be something they compete over. Or just get more and leave them be and let natural selection occur.
2 is good even one is ok i had about 6 hermit crabs before ans some of the ones i had were even alone so try to seperate them in different cages
Separate them before one of them gets hurt! I have a Reptile who lost her leg because of an aggressive reptile brother.
Holy Moly! You have crabs!?
