I was about to replace my hermit crabs food and water when i noticed little gray bugs. My first thought was mites. They are the same color, size, and places mites are found in. I have done little research on how to get rid of them, but it sounds VERY difficult and time consuming. They (5 crabs) are in a 10 gallon tank. Theres a log thing to climb on, 2 huts, food dish, water dish with sponge, and half sand and half sorta dirt and bark mix. I really want to get rid of them but i sounds really hard!! My parents probably wouldnt go through it all becasue theyre just crabs, but they arnt to me and I love them all. Any help and suggestions would be awesome! Thanks!!
