So like a lot of other people, I bought 3 hermies from some store at a beach. They're all unpainted and small/medium. I got the large cage for them.
On the ride home I did some research on hermies and caring for them, and realized I'm totally not prepared for them at all.. I've read all the care guides, learned about temp and humidity, everything. And I'm not prepared for anything! I just got home after a 3 hour drive. The hermies are on my desk right now, just climbing on top of each other/stuff.
The store gave me the crappiest thing ever - a little plastic container with gravel (not even enough to cover the floor too) and a tiny food bowl. I luckily had dechlorinator at home since my dad loves fish (we have a huuuge fishtank). The cage is really small and I was only able to fit a big bottle cap of water into it.
The food that came with the cage is FMR. I saw that that isn't good for them. What should I feed them?
I have a 10 gallon fish tank, but it's almost 5 am so relocating them is going to have to wait.
I don't have anything for the humidity or temp yet!! Not even a way to measure it. I'm really scared that I'm harming the crabs, and I don't know when's the next time my dad has time to take me to the pet store. I feel like I'm torturing the crabs it's horrible

I also have no sand for the little guys. What if they have to molt and I'm prolonging that even more? I feel so evil oh geez. Sorry for writing so much I'm just kind of freaking out and don't know what to do haha
Anyways, any advice would be suuuper appreciated!!
