Hi! I'm new! I don't have hermit crabs, but I think I would like to. There is a 187cm foot tank I have my eye on. I live in Melbourne. (Australia) I have two main questions How many crabs could I keep in a 6 foot tank? Is it possible to keep humidity at a good level without a glass lid? (good level for Australian Land Hermit crabs, Coenobita variabilis) I will, of course, have done a lot of research and have everything perfect with my tank before I even -think- of bringing hermies home, so I'll know if i can get the humidity up high enough without a glass lid anyway, but I'd like to know first if anyone has managed it, or is it pretty certain I'll need to sort out a glass lid. Remember I'm talking Australian land hermies. What is the best humidity for them? Same as for everyone else, 70-80? anywho, hello all!
