Hi! I'm new here and don't actually have any crabs yet. I've been lurking and reading for a while. A friend recently gave me a 55-gallon tank, and I've been planning to set it up with land hermit crabs. My boys are excited about doing this but they're 6 and almost 8 so I plan on being the main caretaker. I was hoping to work on the habitat and then maybe pick out crabs with them over their holiday break from school. There is tons of info on this site! It is great! I was wondering if anyone could give some ideas about how to go about setting up my habitat. I guess what I am wondering mostly is sequence. I read somewhere on here that you should bathe new crabs for mites and only offer an inch of substrate (I think?) if you find mites. I had originally planned on just getting a 10-gallon tank but was then given this 55-gallon, so this is my only tank. So, I guess what I am asking is, would it be adequate to put an inch of substrate in, get the temps and humidity gauges and everything up and running, and then get the crabs, check for mites, and then add to the substrate if they are clean? Should I only offer hideys that are easily sterilized? How many crabs should we get at one time? I'd be glad for any advice. I also wondered about the lighting. The tank is nice and clean but was previously used for fish so came with a hood and lights for that. How should I modify that for crabs? Thanks in advance for your advice!
