A homemade hermit crab habitat! Two water bowls (one fresh and one saltwater), a couple hiding places, some natural stuff for them to climb around on, a food bowl (they eat fruit!), and some shells for them to try on and play with.
(link) World Of Hermit Crabs! - Crabitat Supplies & info ~ NICE CRABITAT ~ EXCEPT: substrate needs to be a minimum of 3x the height of tallest crab (usually min. 6") and 5:1 ratio of Play Sand & EE Coco Fiber ~ for more great PINs w/good links visit @djohnisee ~ have fun!
Here is my 29 gallon crabitat. It has a waterfall in the middle. To make it safe, I have it sitting on top of pottery to keep the sand from shifting and it stops the crabbies from tunneling under it. Then the fall is sitting in a tupperware bowl with big rocks surrounding it so the crabs can't tunnel in the bowl. Nice thick substrate made from play sand and Eco Earth = happy crabbies. http://mydestinysharinghope.com
