As an owner of exotic hermit crabs, I have been dealing with a problem that I have been trying to solve for almost a year. My (20g L) tank is limited in its substrate because I use an under ground heater and i also use calcisand substrate. Because of all this i've found that deepest substrate i can handle while providing enough heat for my Perlatus (Strawberries need 80 degree) is roughly a half inch of sand. Obviously this would cause a problem since the crabs need to borrow to molt. I am one of the people who only isolate their crabs if their sick because i think removing them and their scent from a tank breaks up the social network and cause the other crabs to treat the one out of iso as a passing interloper.Needless to say, more poor crabs have been having to go through above ground molts:wall: . Well (even though this may not be as original as i assume, i found a solution to keep my current tank set-up and also allow my crabs to borrow and molt like nature intended. All i did was take an old case of cd's, took the lid and filled it with bed-a-beast, broke off a couple cork bark ramps, and set myself up a little molt station in my crabitat. I can already tell my crabs are incredibly happy because our largest boy Apollo is already burying himself to start his long awaited molt. And i'm happy because Apollo (who is the largest hermit crab i have ever seen in captivity) is going to molt back the claw he lost while living at Petco!..... it's been four months since he started growing a new jelly limb but he's been pushing off his molt until today!
