I've just become an owner of 2 hermies. I live in the UK and there is no Hermit Crab Association as good as yours so I hope its OK for someone 'across the pond' joining yours?
I'm having a bit of a panic... when I set my crabitat up I added the liquid to de-chlorify the tap water to soak the substrate in (eco earth) and used it straight away. I have read that you should leave the treated water for 24 hours before you use it... Any advise much appreciated!
