I have just set up a 12G using live rock from my 34G cube, i have 2 rock crabs living in the rockwork, i want to keep a watchman goby in the 12G, do you think the crabs will attack him or am i safe? i don't want to get rid of the crabs as they are really cool, they have red eyes and one of them is covered in fine beige hair.
