I got some baby hermit crabs from the LFS
for free to help clean up the bottom of my tank. They only thing i can find from an online source is a scarlet has a yellow face/head are there any other ways to tell the species apart? They are ok for now either way as my tank has no corals or inverts (well 2 turbo snails that are way to big for the hermits for now). I can try to get a pic but they are soo small, think a large MTS shell or as long as a penny.
