Update part 1. So a not so quick tank update. I have the new tank set up with the things I could do for it for now. Two paint dishes serve as pools, they have 4 cups of salt water and 4 cups of fresh water, 6-8″ of substrate depending on where they are in the tank, a hide, a rock, some shells, and a food dish. Don’t worry, I have big big plans for this tank! 
“you need more shells for your crabs!” 🙂 “I know, they are coming via mail, I ordered a 12 pack and it will be here 8/28”
Some things I am going to do/get in the near-ish future, I need a bigger side heater, I need a piece of glass or something to lay on top of the screen lid (right now I am using plastic wrap and am searching craigslist for good deals), I need to get a cuttlebone too… I also have a pretty great build to add a second layer into my tank!

Here is the rough draft, I also found this cool coconut hanging bird toy thing with a bridge, I am gonna see if I can hang it from the top of the tank and have the bridge connected to the climb tree for the crabs? I add the question mark because I need to do some research into safety and how they climb before I go totally nuts. I also want to make a fish net to hang against the back for free time climbing! This is one of those things where if I type all my ideas out, it would be a long post that no one would read.
I will say this, if I play my cards right, I can get a 3 tier set up with lots to explore for my Hermits!
Update part 2! The Hermits!
Here is the thing, there are lots of posts out there with people who are like “Don’t buy hermits, the industry is horrible, if you get them from PetSmart or a pet shop you’re keeping it going, it isn’t fair to the crabs!” I agree with half of this, and for a good reason.
Yes, how hermit crabs get to the stores is depressing and should be stopped.
I think if you do your homework and you are willing to do the things to give the hermit crabs in the stores a serious quality of life situation, I don’t see the harm is buying them. Technically you still are saving them from other people who will keep them in a critter keeper and feed them only pellets.
That being said, I got 4 new ones. My tank is just shy of 40 gallons and this wont be the last tank they ever get into, as the pet keeping grows, so will the tank. I probably won’t get any more hermit crabs, just as they grow, the tank will be bigger. I got two little ones, two not as little ones, and Tamatoa.
Tamatoa has 10 gallons, Kirby has 10 gallons, Turkleton has 10 gallons, Beetle juice and the other crab that has yet to receive a name are sharing 10 gallons, they are the smallest. The one who doesn’t have a name quickly buried himself in the tank yesterday and I haven’t seen him since.

4 crabs, 1 rock
*Here is something you should know* You should not ever dig up a hermit crab. They dig for a number of reasons, and digging a hermit up can harm them! They dig to relieve stress, they dig to molt, and they dig to rest. It is best to just leave them.
