I am wondering if you can keep multiples of spotted porcealin crabs. I am talking about the white and red looking ones. I do have an anemone that they could go into if they want. I guess I am questioning if I can do like 1 or a pair or 3 of them in a 25 gallon tank. I think they are cool and would like to see them moving about. I do have the dwarf blue hermits, not sure if they will mess with them? Thank you!
