Hermit crab climbing toy

I just finished making this climbing ladder. I crocheted it from 10 yards of hemp cord, using a 5.5mm (size I) crochet hook. It's about 13-14 inches long, not including the "tail" bit that is looped over the rim of the tank and taped to the outside. The other end is hooked over the stump of a tree branch. Yes, I worked some glass beads into. Even hermit crabs like pretty things. That's Phredward on the branch--he decided to come out of the moss pit and sit under the bright light.
