About Seth

Seth is a purple pincher hermit crab, aka a Caribbean hermit crab. He lives in a crabitat with a substrate of coconut fibre and playground sand mixed together. I find this works the best for absorbing water, and not collapsing when crabs dig through it.

I had another crab, Peanut, that recently died — possibly due to a failed molt. Since hermit crabs are somewhat social animals, I really should have more crabs in the tank. Unfortunately, I haven’t found a pet store with any in stock lately.

Learn more about caring for hermit crabs with the Complete Pet Owner’s Manual.

Also, don’t get suckered into buying expensive shells at the pet store. Check out Naples Sea Shell Company for great deals on shells, sponges, and decorations.

Hermit crab walking around

Here’s my purple pincher hermit crab Seth crawling around on our carpet. People either love or hate our carpet… what do you think? Leave a comment below :)

Hermit crab climbing the thermometer

Here’s my hermit crab trying to climb up the thermometer. Poor guy — I should get him a hemp net to climb on. When I was a kid I had a cactus in my crabitat, and my hermit crab liked to climb to the top and sit there.
