HCA: Hermit Crab Association

Before such an experiment it'd be better to buy an air purifier for your room where the tank is. Because I can imagine this 'nice' smell of crabs and garlic... I believe, you may choose a good option for you from somewhere like this website https://houseweather.org/best-air-purifier-for-pets/ I have...

First of all, I think, you should try to grow something from this kit, because several times I had nothing after a week of waiting...

We've also purchased 2 crabs as pets for our daughter, she already loves them.
For now she calls them number 1 and number 2, but we are in a process of imagine good names for them
