My son has had land hermit crabs for 4 years. Our recent family vacation to Myrtle Beach SC. yielded some awesome shells and some unexpected hitchhikers(marine hermit crabs). I have always wanted a salt water aquarium and now I had motivation.
My son and I together now have
2 Long Clawed Hermits brought home from the shores of Myrtle Beach SC.
2 Blue legged Hermits
1 Scarlet Reef Hermit
1Dwarf Red Legged Hermit
1 Unknown (I call him The Ghost)
All of my pics can be found HERE
